New problem with 20110803

New problem with 20110803

[Yaakov (Cygwin/X)]

There's another problem with the 20110803 snapshot.  When a fork fails
with the following message:

       0 [main] cmake 5088 child_info_fork::abort: address space
needed by 'cyggcc_s-1.dll' (E20A0000) is already occupied

ALL user processes except for mintty, even those in other terminal
windows, are "Stopped" (prefixed with "S" in ps) and do not respond to
Ctrl-C or the like.  A new terminal can be started, but then all
fork() calls fail with:

      0 [main] sh 4680 fork: child -1 - forked process died
unexpectedly, retry 10, exit code -1073741819, errno 11

Currently-running services do not seem to be affected.

I can't reproduce this.  Only the process which gets the "address space
needed" message is hindered, not any other process in any other terminal
window.

And, indeed, since the only thing I should have done was expose the
error message to the console, it's hard to see how it could affect
other processes.  There should be no change in behavior other than
writing the message to stderr rather than just as an unseen (even
if you were doing 'strace -m all') strace message.
