I have given a quick look... I don't know much about python, apart from 
the fact that it's an interpreted language, with its command line & parser.

The python files have mutex locks all over the place:

   93     # these locks are to be shared by all PyMOL instances within a
   94     # single Python interpeter
   95 
   96     _pymol.lock_api = threading.RLock() # mutex for API
   97     _pymol.lock_api_c = threading.RLock() # mutex for C management of python threads
   98     _pymol.lock_api_status = threading.RLock() # mutex for PyMOL status info
   99     _pymol.lock_api_glut = threading.RLock() # mutex for avoiding GLUT



In __init__.py, there's also:

  76     # standard input reading thread
   77 
   78     _pymol._stdin_reader_thread = None

So it looks like it's multithreaded, with a thread dedicated to waiting for the input.
