A while back, I remember running samba with the configuration option "panic action = /usr/bin/X11/xterm -display :0 -e gdb ...". On a segfault, you'd get a happy little xterm ready to go. Never managed to recover an operation from that window, though.
I have caught a condition in StumpWM (a window manager written in Common Lisp) and done something useful with it. A completely different beast. Practical Common Lisp has a solid example that may be a bit enlightening (http://www.gigamonkeys.com/book/beyond-exception-handling-co...).
