I believe it's XGrabPointer, which causes all mouse and/or keyboard
event to be delivered to specific application. If that application is
stopped by gdb, it means, in effect, that events are not processed at all.
I have no idea if that's the cause, since the emacs diff posted in another
email does not have any apparent locking thing, but it very likely.

I believe this is dependent on what toolkit the application being debugged
uses, not what other applications are running.
