Someone asked if anyone had thought about adding swapping on the ST version
of Minix. Well, I had thought about it for 2 minutes and decided it wasn't worth
any more effort. The ST process image contains absolute address references
which would require that the process be swapped in at the exact same position
in memory that it was swapped out of. This could be quite difficult to
arrange if the memory freed by swapping was fragmented as new processes were
created and destroyed. It really doesn't seem to be worth the effort.

Naturally the PC version doesn't have this problem, and with typical PC
configurations having at most 640K available it might be worth while.
