save and regerate the current screen before and after a command

Yes, but not all terminals provide the ability to copy one screen to another,
thus making the screen switching solution terminal-dependant (and therefore
unusable by the general public).

One solution would be for the kernel to map all characters written to tty's,
but this would involve linking terminal capability into the kernel which would
mean re-linking every time a terminal was changed around (yuck!).
