I remember a program for the Amiga that would swap a process entirely into a file on disk so that you could continue it later (even after a reboot) but it had a lot of trouble with memory fragmentation. I think the only times you could restore a process were after a fresh reboot (if you were lucky) or right after you swapped it to disk, so it was not very useful.
Also, I noticed last year on a system running Linux 1.2.1 that occasionally after the system crashed (the CPU fan burnt out, causing numerous random crashes before I discovered what was wrong), it seemed that some memory was paged in from the swapfile on the next reboot, as shown by some very informal testing during which I did something to the extent of "swapoff /dev/hdxx; mkswap /dev/hdxx; shutdown -r now".
