I saw a message in comp.unix.wizards claiming the ST version
of Minix implements context switching by copying the active process
in and out of a fixed region of memory. Is this true?
It would take about 100 millisecs to copy a 100k process in any out.

I got the impession from an earlier message that copying was
only done for forked (but not exec'd) processes.

Can someone clear this up?
