The subprocess code does not include "import bpy". The multiprocessing 
module (using the 'spawn' method) re-executes the *module which created 
the subprocess* inside the subprocess, which currently has to import bpy 
to get the path to the python interpreter executable. This can be worked 
around by creating an "in-between" bpy-free module which creates and 
starts the process object (and is passed the path to the python 
interpreter from outside). However, after doing that, multiprocessing 
appears to fail to find the python file to execute?
