Good question! Not much probably. To be honest if every platform I was interested in was a unix I would have just used fork. In fact fork is cleaner because I could use a local variable for the parent pipe and the child process would be able to use this directly without faffing about with locks and stuff. Anyway, using tcp for communication between processes on windows was just clunky enough that I wondered if I how difficult it would be to run a bunch of factor vms in the same process, and that's what started me down this road. I'm still not sure if running many vms in a process is as useful as it sounds, but the reentrant code changes are a step towards true native threading so I guess if it doesn't work out it's still a useful step.
