Yes, this is known as process checkpointing. There's been a lot of
research into it but every approach has its limitations.

Environments like User Mode Linux, Mosix or Bochs could make it easier,
though not as easy as a nice simple process without shared memory,
threads, network connections, etc. A more mainstream approach is
suspend-to-disk of the whole system, which people use every day on
laptops, but desktops can be capable of, too.
