Damn - I actually paused to think before I typed the Holy Protected Word
And All Its Homonyms, Antonyms, freakin lawyers - backed by Billy's
Billions... maybe DOJ will point Ashcroft at them...
Anyway, I used to use a program for very early DOS machines called
Software Carousel, which basically freeze-dried up to 12 snapshots of the
current TPA and chunked them onto the HD... and assigned each frozen
session to a PF key. So you could switch back and forth between tasks
easily.
Obviously the 'frozen' tasks were just that: there was no backround
processing, they remained suspended until that particular task was brought
back into working memory from the HD.
