He *might* be right about that -- certain OSes have a fixed limit,
say 32,767 pids in use at once.

After a while, the OS will start re-using old pids which are no
longer in use. I've seen numbers in the 30,000 range, but I can't
recall seeing anything over 32,767. And I definitely *have* seen
newer programs running with a pid in the hundreds, despite having
other programs in the 20,000 still running.
In short, this is exactly the way that unix programs are supposed
to act.
