Whenever there's a problem, create simplicity. I would recommend not
using the file-from-socket method, and simply using pickle.dumps() and
pickle.loads() to pickle to/from strings; those strings can then be
sent/received over the socket using standard recv/send functions.

Also, Chris Rebert's idea is a good one, and worth trying.
