Interesting, I was playing around with KDE and compiled the Kjewel source
code (its a tetris clone). When I run it, it doesn't have its puzzle
pieces, but it also causes the entire window system to completely lock up.
No keyboard events appear to be getting through. If I telnet into the
system and kill -9 the process, everything comes back to normal. Its a very
strange thing that a user process should be able to do that... (this is 4.9
w/ KDE 3.2)
