I would like to spawn off multiple instances of a function and run

Currently I'm doing this by calling them as sub-processes

the function call?
Try using the python standard threading module.
Create multiple instances of Thread with target=your_function
Maintain a list of these new Thread instnaces Join (wait) on them.
pydoc threading.Thread
The disadvantage of threads in Python (CPython, actually) is that
there's the GIL (Global Interpreter Lock), so you won't get any speed
advantage if the threads are mostly processor-bound.
