Dear Bug Team!

When deleting a large number (200,000 ish) of characters from a shell
window Xemacs hangs. I am using shell-mode in xemacs-base 2.10. I've
not experienced this problem with prior versions of xemacs/lisp.

Set mark at end of buffer. Move to top of buffer. Ctrl-W.

prstat shows Xemacs running 23% cpu. It (the xemacs) has been hung for
quite some time.

PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
6910 lkashley 2063M 2052M cpu1 40 0 0:18.38 23% xemacs-21.4.20/1

Any thoughts on how to tackle this would be appreciated.

Loren
