commit 88bacc49f06da5927f716869f5a32672a8297ed0
Author: Chase Douglas <chase.douglas@canonical.com>
Date: Wed Apr 4 15:29:42 2012 -0700
os: Add -displayfd option
This option specifies a file descriptor in the launching process. X
will scan for an available display number and write that number back to
the launching process, at the same time as SIGUSR1 generation. This
means display managers don't need to guess at available display numbers.
As a consequence, if X fails to start when using -displayfd, it's not
because the display was in use, so there's no point in retrying the X
launch on a higher display number.

This allows the server to call GetTimeInMillis() after each request is

Keep SIGALRM restart flag after Popen
Commit 94ab7455 added SA_RESTART to the SIGALRM handler. However, the
Popen code tears down and recreates the SIGALRM handler via OsSignal(),
and this flag is dropped at this time.
Clean the code to use just a single codepath for creating this signal
handler, always applying SA_RESTART.

Allow system call restarts upon signal interruption
The X server frequently deals with SIGIO and SIGALRM interruptions.
If process execution is inside certain blocking system calls
when these signals arrive, e.g. with the kernel blocked on
a contended semaphore, the system calls will be interrupted.
Some system calls are automatically restartable (the kernel re-executes
them with the same parameters once the signal handler returns) but
only if the signal handler allows it.
Set SA_RESTART on the signal handlers to enable this convenient
behaviour.

Don't frob timers unless SmartSchedule is running
commit 2338d5c9914e2a43c3a4f7ee0f4355ad0a1ad9e7
Author: Arjan van de Ven <arjan@linux.intel.com>
Date: Sun Oct 28 09:37:52 2007 +0100
reduce wakeups from smart scheduler
The smart scheduler itimer currently always fires after each request
(which in turn causes the CPU to wake out of idle, burning precious
power). Rather than doing this, just stop the timer before going into
the select() portion of the WaitFor loop. It's a cheap system call, and
it will only get called if there's no more commands batched up from the
active fd.
This change also allows some of the functions to be simplified;
setitimer() will only fail if it's passed invalid data, and we don't do
that... so make it void and remove all the conditional code that deals
with failure.
The change also allows us to remove a few variables that were used for
housekeeping between the signal handler and the main loop.

**Note**: The above change also required ABI changes in hw/nxagent/.

So, like, checking return codes of system calls (signal, etc) is good.
Also, only restore an old signal handler if one was actually set
(prevents the server from dying on OS X).

Ignore - not just block - SIGALRM around Popen()/Pclose().
Because our "popen" implementation uses stdio, and because nobody's stdio
library is capable of surviving signals, we need to make absolutely sure
that we hide the SIGALRM from the smart scheduler. Otherwise, when you
open a menu in openoffice, and it recompiles XKB to deal with the
accelerators, and you popen xkbcomp because we suck, then the scheduler
will tell you you're taking forever doing something stupid, and the
wait() code will get confused, and input will hang and your CPU usage
slams to 100%. Down, not across.
