DOS 4.x has been out for a while but as far as I can tell is only sold in
Europe.  It's a multitasking version of DOS, sort of like Digital Research's
Concurrent DOS.  Microsoft makes no secret of it, but they don't seem to be
very enthusiastic about it either.  My impression is that it doesn't swap,
it just partitions up whatever memory you've got.  So much for breaking out
of 640K.
