Good points. If we stayed restricted to large code segments only, however,
then we could run much larger programs (like the bcc compiler, for one),
if we restricted ourselves to the following:
o Dont' swap code that has the multi-code segment bit set in the exe hdr.
(This isn't that big a deal, especially if it lets us run real programs...)
o Fork isn't a problem if we use shared code segments, and don't have
far data pointers.
