I have an i386 machine and Firefox can kill my box lately on occasion
too...  As does compiling, using amule, using totem, running portsdb,
and many other programs.  Heck, even logging in and firing up evolution,
xchat, and gaim simultaneously have locked my machine.  All of these
don't crash my machine 100% of the time but still often enough.

I haven't gotten this to work myself but I really haven't tried much
with it.
