Not really. You could fiddle the code so that every x seconds, every
single routine ran (just a little bit of it) provided the whole
routine fitted into one page, that would stop a Least Recently Used
algorithm from kicking it out. Downside is much greater real memory
useage.

No it is an OS thing.

Timing. Disks are slow and it takes time for processes to be swapped
back it. A timer may expire in the meanwhile.

Another reason is Network Neighborhood sucks, even between Win95
machines. There may be something just slight that upsets it.
