Node Locking
Another feature provided by the BNode class is "node locking": Through BNode's
Lock() function you can restrict access to the node. The lock is removed when
Unlock() is called, or when the BNode object is deleted.
There is still something wrong with locking though. For example, it looks like
WriteAttr() fails on the node when we lock it (File Busy) but it should not.
The lock acquirer should be able to call WriteAttr() on it.

or else the server will keep working with the state and especially a clipping
region which should not be effective anymore. This fixes one problem I could
observe with my test app.

PushState() should be at the top of the state related methods.

Firefox. It stores the active clipping region of a view when Draw() is
invoked, and uses that for asynchronous drawing. The test already shows
a couple of problems. When PushState() / PopState() is used, it is not
equivalent to ConstrainClippingRegion(&someRegion) /
ConstrainClippingRegion(NULL). Another problem shows when adding delays
(currently disabled), there should not be any difference, regardless of
how much delay is inserted into the asynchronous drawing.

possible on the server side (for example Show() and Hide() need to be
immediate). But also SetViewColor() and a few others. This fixes the
bug encountered in Pairs.
* Removed NOTE in DrawAfterChildren(), since it was outdated.
* Corrected a typo in a comment.

* Added RLIMIT_CORE case. We don't support core dumps, but setting them
to disabled shouldn't fail anyway.

* Publish /dev/ptmx. Opening it will open a fresh pty master. In
principle /dev/pt/ is obsolete now, but I guess we keep it around for
compatibility with BeOS. Though there shouldn't be many applications
opening a pty, that we might be interested in...
* New ioctls B_IOCTL_GET_TTY_INDEX (returns the tty index) and
B_IOCTL_GRANT_TTY (grants tty slave access rights).

* It is possible to acquire a tty that is already open, iff it is not a
controlling terminal yet and the process is a session leader.
* Also set the terminal process group when acquiring a controlling
terminal.
telnetd/login and sshd are a lot happier now (and so am I :-)).

cleverness to reschedule only, if it actually unblocked another thread.
Should have been the reason for #2152 (overall slowdown).

* remove_transaction_listeners() was checking the events_pending field without
holding the sNotificatonLock - that should have been harmless (as we're in the
middle of deleting the transaction), but it now looks better.

later quite often.

AF_INET socketpair()s -- not really needed, but probably nice for
testing.

adding a block to its array. This could cause all kinds of trouble, and
fixes at least a part of #2148.

instead, it will now use the image_id parameter to store errors in.
* find_instantiation_func() and validate_instantiation() will no longer
overwrite errno with B_OK.
* Made private functions static, and moved them to the top.
* If the class name starts with '_', it will now try to add a BPrivate namespace
in case it could not find the class. This should help with the compatibility
issues Shinta reported (also part of ticket #2086).

find one. This fixes#2086.
* Cleanup.

write as much as they can and return B_WOULD_BLOCK, if that wasn't the
whole request.

succeed after we have successfully sent the first buffer, even if not a
single byte of some following buffer could be sent. We should probably
even succeed whatever the error code -- not sure what is the reason
for only doing that for B_WOULD_BLOCK and B_INTERRUPTED.

* don't exit just in case we can't load the icons,
instead draw an string what the default printer is
* call create_directory only if the printers dir does not exist

* Add spacing around the tab view.
Thanks, Philippe! BTW, the tab view will come in handy again, now with the
additional options that sub-pixel rendering is going to offer... :-)

the new node (which also has a reference) was removed again.
* Added debugger command "net_buffer_stats" which prints the allocation
counts of net buffers and data headers.

This fixes race conditions. The OpenSSH tests don't hang anymore --
instead they run the system out of memory, apparently due to a net
buffer/data node leak.

effect that any on the fly changes such as the color drops allowed
by the Activity Monitor replicant were discarded. Fixed.

* The "net" driver is now also loaded.
* The node tree is now dumped.
* If registering fails, the node is now removed from its parent again
(for now, correct would be to release it).
* device_node::_RegisterDynamic() now also checks for the driver path.
* _RegisterFixed() no longer calls supports_device() - since it has been
directly specified, we will assume the user knows what he is doing.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25112 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added support for non-published condition variables. One has to call
Init() on those, and add entries directly with the
ConditionVariable::Add() method.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25110 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the object pointer passed to thread_prepare_to_block() const, so
that strings can be passed without casting. Passing a string could
maybe be made a convention for THREAD_BLOCK_TYPE_OTHER.
