I've heard it said that you can do interesting things on SGI's when you
get a large core dump happening and the bus gets flooded.  I've no idea
about which version of IRIX...

I didn't bother to chase up on details, but someone might like to play
around with 50MB (you get the idea of what I mean by large) core dumps
and seeing what happens when you attempt other diskio at the same time.
