	From my reading, 'shadowing' consists of copying the current
running process into the memory it was in before a fork... so there
is a big memory copy going on every process swap.  This apparently
causes problems with programs like kermit, which do a fork and
run two processes.

	808x parts don't have this problem because the process can
be moved to another place in memory and 'relocated' via the segment
registers, so that the forked copy can work in a different place
in memory.
	Am I correct???
