I don't know enough about the guts of unix scheduling to write one
myself, but I'd certainly be interested in seeing such a document
if some more knowledgeable soul were to write one.

I'd especially like info pertaining to IRIX. I've had no trouble with
the Solaris client, but the IRIX client has been somewhat more reluctant
to relinquish the CPU at times...

I assume this is supposed to be true of nice()'s everywhere?
