This sometimes happens to me, too.  (The magic numbers are
18.54, HP9000/350, HP-UX6.5, and X11.)  I have no idea what
causes it, but I've found I can unwedge emacs by sending
it a SIGALRM signal:  "kill -ALRM <pid>".  This probably
does something terrible to emacs's internal state, but so
far I haven't noticed any problems.
