Chortle. I can knock Solaris boxes over with crashme about once every
10 minutes. Linux/Sparc stays up.

Lots of people do a lot of stress tests. This includes the fact the net
changes often get tested on, that Davem runs horrible
sparc torture tests and most of us make heavy use of big iozone and
crashme runs

Linux 2.1 is to a great extent that stuff ready for testing. If you want
to put a bunch of people together to write the "brutalize kernel" suite
please do - it would be a great project for use on all OS's
