On MS Windows, Emacs sometimes hangs when shutting down or logging out.

(This build includes 5114b3a204..: Eli Zaretskii 2017-02-23 Avoid
quitting inside a critical section on MS-Windows, see #25279).

I've included backtraces for all the threads having Emacs functions on
the stack, because I can't tell which are deadlocked, if any. (2 and 3?)

Also got these from thread 2, frame 2.

(gdb) print crit
$1 = (CRITICAL_SECTION *) 0x401bc6a20 <crit_real>
(gdb) print crit_real
$2 = {DebugInfo = 0xffffffffffffffff, LockCount = -1, RecursionCount = 0,
  OwningThread = 0x0, LockSemaphore = 0x0, SpinCount = 33556432}

In the nine months since Ken's change, I've noticed a problem with
Emacs twice.

Then I guess it would be better to just push those changes and see if
they do any harm.

I can't get my head around the idea. If we don't care whether or not
the action in question has finished when SendMessage returns,
then why are we using SendMessage? And if we do care, then
shouldn't I expect weird bugs caused by timing out when the system's
under load?

If a window procedure doesn't process messages for more than 5 sec,
Windows will put "Not Responding" on its caption bar.  So I think the
100 msec number in Ken's patch should be changed to something like
6000, and then we are fine, because even on a busy system this should
be long enough.  And if Emacs (and the OS) is about to shut down, it's
even less of a problem to ignore a message that timed out, IMO.

I've pushed the patch (with 6000 msec) and am closing the bug. Richard, please reopen if you ever see the problem again.

I'm leaving the sleep(1000) in w32_wnd_proc, at least for now, because I want to find out about it if the problem isn't really fixed. Maybe I'll add a FIXME comment.

Ken
