- I object to one claim made by Henry Spencer on job suspension:
- >Note that this suspension facility isn't very useful in the absence of
- >multiplexed interaction -- you can't *do* anything to a suspended process
- >without access to another (real or virtual) terminal -- but the two concepts
- >are nevertheless quite independent. There is no need to confuse them.
-
- Completely independent of terminal interfaces, job suspension is a
- useful feature. In particular, I have a batch queue mechanism in
- mind on 4.2bsd UNIX which suspends batch jobs when the interactive
- load gets too high, and restarts them (sending SIGCONT) when
- the interactive load drops again. This control can be done both
- by an operator and by a daemon, and has no notion of controlling
- terminal for the batch job.
-
- As Henry indicates, job suspension and multi-process control are
- two different items. Even though job control may not be the only
- or best way to implement multi-process control, job suspension is
- an important feature in its own right.
