Probably a really dumb question, but I found TID1202963 that said when in
debug mode, if you type EIP=CSleepUntilInterupt, and then g to quit, you
can abend the process that has hung the server.

I wanted to try in on a 6.5 server just to see it work, but it hasn't got a
process that has hung, and when I tried it anyway, it came back Invalid
Change request syntax.

So, do I have to have something hogging the CPU to be able to do this, and
does anyone have a way to do this easily (ie go int debuig mode and type a
command first)
