include the guard pages. Adjusted the kernel and boot loader code
accordingly -- the guard pages size is added/not removed respectively.
The stack size passed to _kern_spawn_thread() is now the actually usable
size, and it is no longer possible to specify a size smaller than or
equal to the guard pages size.
* vm_create_anonymous_area(): Precommit two pages maximum -- a stack with
only one page usable size obviously doesn't need two pages.

userland. E.g. preparing a signal handler would terribly go wrong, since
we don't have a userland iframe. This fixes bug #2562 and maybe also
#2522.

of the current search. If new files match the pattern, the appear in the
results, or are removed if they don't match anymore. The results also
adapt to changes in the files.
Basically, I added another iterator that is also used to track changes when
node monitor events arrive. Only those changed files are grepped again after
a timeout of .5 seconds when no new node monitor events pour in.

* In case of a kernel iframe the iframe is shorter -- fixed the output
accordingly.

* The B_QUIT_REQUESTED message never arrived for me unless I unlock the
BLooper again, then it works as expected.
* The B_QUIT_REQUESTED handling accessed fOwnsLooper after deleting the
object.
(Review much welcome - I don't understand the purpose of locking the BLooper
at all before trying to use a BMessenger to send it a message.)

* The blocks beyond that would be potentially read in smaller chunks than
anticipated, too.

without filling it with zeros (ie. make use of B_STAT_SIZE_INSECURE).
* Added TODO that closing the file descriptor in swap_init_post_modules()
(that should probably renamed to swap_init_post_boot_device()) is not really
a good idea.

* Beginnings of node monitoring support. Currently disabled, but detects
new, changed and removed files. Folders untested yet. There may also be
a problem with the toplevel folders when a pose selection message is used.
That's untested too as of yet.
* Removed some superfluous whitespace.
* Small refactoring in FolderIterator to access some stuff from the outside
as well.

which are now only used for directories and for files smaller than 1 MB.
* For files between 1 MB and 32 MB 512 KB are used as preallocation size,
everything beyond that will get a 1/16 of their file size, ie. 4 MB with a
file size of 64 MB, 64 MB with a file size of 1 GB.
* This should help a lot with fragmentation of large files when they are written
synchronously.

block_run.

StartWatching() before and the BPathMonitor stuff is therefor not initialized.

now a lot earlier.
* That makes it now possible to use modules pretty early in the kernel (like
before timer_init(), or int_init_post_vm()).

object.
* Improved check that enforces search pattern history limit to also handle
the case when the limit is changed in the source.

* FileIterator is now a mostly abstract interface
* FolderIterator is the currently only implementation (there could be
MessageIterator for an even better separation, which would read the top
level search folders from the BMessage with the selected poses, but it
would mostly use the same code for traversing the subfolders anyways so I
left that for the time being.)
* The Grepper and FolderIterator now copy the current settings from the Model
at instantiation. Since they run in a separate thread and the Model may
actually be changed from the Window thread, I think this is just a cleaner
and more safe solution.
* Cleanup here and there.

* Added file_map_set_mode() function that you can use to keep a whole file
cached. This is needed for the swap file support: FILE_MAP_CACHE_ALL will
not only precache all file_io_vecs when called, but it will also cause all
file_map_translate() calls to fail that would require further caching (ie.
if the file size had changed).
* Updated the fs_shell file map code to the latest one (with several bug fixes).

* Keep track of the stack space actually allocated for the cache and let
Write() fail when we've already allocated as much as reserved.
* Added second phase of swap initialization (swap_init_post_modules())
which reads the virtual memory driver settings and creates/resizes a
swap file. ATM truncate() is used to resize the swap file, but that is
a bit slow. We should probably introduce a VFS function to use BFS's
fast method.
This should make swap support work somewhat, but since swap space is
never freed ATM this would be a relatively short pleasure. Still
disabled by default.

* bfs_open() was leaking the already allocated cookie in several error
conditions.

actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

* When do_iterative_fd_io_iterate() fails, we must not invoke the
supplied finished hook explicitly, since it is invoked indirectly by
request->SetStatusAndNotify() anyway. Should fix#2557.
* We must detach the descriptor putter as soon as we have adjusted the
request's finished callback, since that will put the descriptor.

and size of the double fault stack.
* is_kernel_stack_address() does now also check whether the given
address is on the double fault stack. This fixes stack traces on
double faults, which were broken (i.e. went only to the double fault
iframe) since we started checking whether the addresses are on the
kernel stack at all.
