Yes I know we don't care about Windows for this particular project..
I think mixing multiprocessing and fork should not harm, but probably
is unnecessary since I'm already in another process after the fork so
I can just make it run what I want.

Otherwise is there a way to do same thing only using multiprocessing?
(running a process that is detachable from the process that created it)
