Subprocesses with pytorch #43

This adresses #38. Switching the multiprocessing method from fork to forkserver seems to do the trick (tested with a crappy NVIDIA GPU). Detail of the methods.

In the same time, I tweaked to code to stop using deprecated methods, eliminating the current warnings.

It seems that the multiprocessing version relies on cloudpickle. Shouldn't that be included in setup.py?

You're right, cloudpickle should be in setup.py. I will add it.

I'm impressed btw. Did not think this problem would get fixed anytime soon! :+1:
