Well... My machine is not that big :-)

I tested it with a P166, 64MB RAM, 45MB Swap, libc5, kernel 2.1.12[0-3]
and always from inside KDE (X, etc). I tried to use it in a "running"
environment.

It *always* crashed my system. I even let my machine on for 5 hours with
this program running and it did not recover.

Could libc5 be the problem?
