Dear Bug Team!
I've noticing occasional deadlocks between XEmacs and the X server.
Every time I can remember it happending I've had gdb-mode running in a
buffer (though I'm usually not actively accessing that buffer). It
may be correlated with starting a second frame on that same process.
An strace of the running process shows it hanging on a select of the
unix socket that corresponds to the X server.
I've found this:
http://list-archive.xemacs.org/xemacs-patches/200212/msg00029.html
which seems related, but as you can tell by the data below I'm running
21.4.12 (which supposedly has things much better than before).
I'm very interested in having this problem fixed, but if there's a
workaround to break the deadlock, I'd love to hear about that, too.
Also, if there's reason to believe that 21.5.x is less prone to this
bug, I'd considering using that branch.
Finally, if you have instructions on how better to reproduce the old
bug, I'm happy to work with you to investigate further.
Thanks!
Greg
