[issue37292] _xxsubinterpreters: Can't unpickle objects defined in __main__

The relevant code for the multiprocessing example seems to be in Lib/multiprocessing/spawn.py. I think I get what it's doing, but I'm not sure whether we actually need something similar for subinterpreters. Any thoughts @eric.snow?
