Of course, swapped - out processes better had not be interactive, or users will complain very loudly about response time. An operating system which does stuff like that had better distinguish between interactive and batch jobs; I'm not aware of any UNIX variant which actually does so. I know MVS does, and I'm pretty sure VMS does, too. -- Thomas Koenig, ig25@rz.uni-karlsruhe.de, ig25@dkauni2.bitnet The joy of engineering is to find a straight line on a double logarithmic diagram.
