Hmm.. I don't get seg faults while resizing, but every once in a while 
I'll alt-tab to an xterm and start typing, only to have the xterm 
evaporate. Once it also happened to emacs, which left both emacs and the 
terminal pretty well unusable. Unfortunately, I don't get a stack trace 
or any messages in /var/log/XWin.*.log. It just goes away.

I'd never seen this behavior with 1.8.2-0 (or earlier), so I'm rolling 
back to it. I'll holler if the problem continues.

Ideas?
Ryan
