its shells has been terminated. Usually the thread reading from the tty
master would notice when all slaves have been closed, but they won't be
closed when the shell started a background job that's still living.
Unfortunately there are race conditions in the terminal that can lead to
deadlock when a session is closed. The service threads usually happily
lock the window, while the (locked) window would wait for the service
threads to quit.

the host platform's <signal.h> to build the signal name array from. We
use a hand-edited signames.h when cross-compiling for Haiku, now.
The shell does now show the correct signal names when having been
compiled under Linux. Moreover we avoid bug #1428 (mksignames being
broken under FreeBSD).

is used instead of death_entry for team::dead_children.
* Added team::{stopped,continued}_children, which, analoguously to
dead_children, are used to track the state of stopped/continued
children.
* A team does have a job_control_entry, which is allocated at team
creation time. It will be inserted into the parent's
{stopped,continued}_children lists as the team's main thread is
stopped/continued and removed when waitpid() retrieves the child
state. When the team dies the entry is detached from the team and goes
into the parent's dead_children list.
* Removed the wait_for_any field from team_dead_children. It was solely
used to avoid deletion of the contained entries in certain situations.
wait_for_child() (the waitpid() backend) always deletes an entry now,
regardless of whether other threads are waiting; that's in
accordance with the waidpid() specification. wait_for_thread() removes
the entry only, if the caller is the parent of the respective team.
* Introduced team_set_job_control_state() which performes the job
control entry transitions between the respective lists and wakes up
threads waiting in wait_for_child(). It is invoked on team death and
when the team's main thread receives job control signals.
* Reorganized wait_for_child(). It handles WCONTINUED and WUNTRACED now,
too. Removed a block that interpreted the supplied ID as thread ID.
* Added missing parts in waitpid().
Job control starts to work, though it seems to have some glitches.

acquires a spinlock all in one.

aggregated member to a pointer. I'm very close to starting to convert
all remaining .c to .cpp files. :-/
* Got rid of the "waiters" field. It was only written, never read.

not found or Unpublish()ed while waiting), or B_INTERRUPTED

access the pci_device object.

* Removed left-over commented C implementation.
* It is now possible for a thread to wait for more than one condition
variable at a time.
* Made waiting for condition variables optionally interruptable.
* Renamed Notify() method to NotifyAll() and added a NotifyOne(), so
that it is now possible to wake up only one of the waiting threads.
Pretty much untested at the moment.

have become more expensive, so maybe it is better to do what I proposed
in the ticket comments, and move the rounding of drawing command coordinates
into ViewLayer::ConvertToTopForDrawing() instead of handling it in
DrawingEngine and Painter

coords in this way. BRegion does a different rounding, also compatible
with BeOS. I added an explaination. This fixes one _part_ of #1426, which is
that Sudoku doesn't invalidate more area than intended (or at least it works
as it does on BeOS now). The second part of the bug though is that the server
has been preventing the drawing of lines and rects in a certain way, in another
words, the part of the bug I fixed should not have been a problem in the first
place if the clipping would have worked correctly. I believe the problem shows
when the drawing commands contain fractional offsets. The rounding happens in
the server, but maybe too late (after comparing with the clipping region). It
could also be a bug in our BRegion implementation, I need to check my new
implementation behaves exactly like BeOS in the Intersects() and Contains()
methods for fractional coordinates parameters. Anyways, at least the visual
problems are gone.

for three different levels (from "Very Easy" to "Hard"). Have fun!
* Feel free to do a nicer icon!
* Stack.h is actually verbatim copy of a kernel header which we might want
to move to a more public place (like shared).
* ProgressWindow is taken from ShowImage, but adapted to suit different
needs.
* It seems to trigger a bug in the interface kit or app_server: when moving
the mouse around, the right border of a field is sometimes lost. This
does not happen in BeOS, and there is actually no code that looks responsible
for this - it might be an off by one error in the region code, though?

* cloned pads are now opened at an offset, otherwise one wouldn't have any
