Here is where 'multiprocessing' assembles the command line to spawn
the subprocess (Windows version):

if getattr(sys, 'frozen', False):
return [sys.executable, '--multiprocessing-fork']
else:
prog = 'from multiprocessing.forking import main; main()'
return [_python_exe, '-c', prog, '--multiprocessing-fork']

It's in multiprocessing/forking.py. As you see, 'main()' is run in
the separate process first thing, which calls self._bootstrap().
Perhaps you can muck around with that and hook it into your IDE
somehow. Even using pdb, which is just a module in Python itself, was
a bit tricky. Let is know what you learn.
