I'm curious if anyone else is seeing this.
The way I can reproduce this behavior is by using any sort of program
which generates XInput events very rapidly (in my particular case, the
program was plover). Below the fold is a test program which pretty
reliably hangs rxvt-unicode (you'll need python-xlib). Can anyone else
try to reproduce?
Note: if you're running a WM like xmonad which can't close the terminal
if it hangs, use 'xdotool selectwindow windowkill' to kill it.
