You could. What you'd have would be a setup where the subprocess is utterly independent of the parent; the fact that they both happen to be written in Python is almost immaterial. Figure out some way of telling the subprocess what it needs to do (eg command-line parameters coming through into sys.argv), and getting a response back (eg writing something to stdout before terminating), and then you can use the subprocess module to spin off the pypy processes, then (maybe after doing some other work) wait for each of them to finish. The subproblem solver could be written in any language at all, here; there's complete decoupling. If you need to pass a lot of info down into them, or up and out again, you'll need to serialize it all into JSON and use stdin/stdout, or something like that. Takes some care, but it works beautifully... I once had a "Python in Python" setup like that to make my Python-based web site trigger something in a newer version of Python than was shipped with my OS (think of a 2.7 invoking a 3.5 script - I don't remember the actual versions but it was something like that).
