Early TRS-80 Model 16 Xenix had process number limits. Linux has come farther
than that. :-)
Process IDs are two bytes and automatically wrap around, as they do in any
(working :-) *ix.
...someone will have to explain to me why "at" is so anachronistic. "atrun"
went out with System III; it should be part of cron now.
