If you'd like, you can turn a socket into a file-like object using its
makefile() method. An Unpickler will know when to stop reading from
the file (there's a STOP character in the pickle format). David
Beazley gives an example of this approach in Part 7 of "Generator
Tricks for Systems Programmers": http://www.dabeaz.com/generators/Generators.pdf
