Phil Dawes spent some time working on a patchset to allow starting multiple
Factor VM's in their own threads. You can see a test for it here:
https://github.com/slavapestov/factor/blob/master/extra/native-thread-test/native-thread-test.factor
I'm not sure if we merged all of his patches, but you can search his name
on the mailing list and there is a couple links on the issue I filed to
look into this:
https://github.com/slavapestov/factor/issues/1161
I imagine you want to build something a bit like the Python multiprocessing
module. It shouldn't be that hard to do, but might require building a few
things. The server framework is pretty flexible and well tested (
factorcode.org, for example, runs on a Factor http server). We have
serialization code, a few examples of RPC, but you might have to put it all
together for your needs. Would make a great contribution! Concurrency is
one of priorities after releasing a small 0.97.1.
Best,
John.
