Thanks for the pointer; that fixed that problem.

Perhaps I should have been a bit more specific: "Is this easy and cheap?" :-)

I noticed the ulimit(2) call shortly after I posted this, and found the
enormous value that the limit is set to with a short C program. I'm glad NCR
did something reasonable with this feature, as opposed to a lot of other
System V vendors...

I guess I'll have to watch out for the 1 meg per-process limit. At least
there's a good technical reason for it.
