So long as you don't mind using 2.6 kernels and/or not having 9 things that a process could do that might stop it migrating (such as using I/O directly, having a memory-mapped file, etc.).

There's plenty of reasons that something like ksplice would be superior under certain workloads than trying to revive a (dead) concept / software project.

There are hurdles to doing it right now, but no fatal flaws in the concept. ksplice may be "superior under certain workloads", but process migration is a good design idea that will be implemented anyway on the long term.

CRIU can do this and is very much alive.
