Merge pull request #1440 from jstenar/win32-testing Fix for failing testsuite when using --with-xml-coverage on windows. This is necessary to get the shiningpanda testing on windows to work. Without the fix all tests fail.

"""Utilities to enable code objects to be pickled.
Any process that import this module will be able to pickle code objects. This
includes the func_code attribute of any function. Once unpickled, new
functions can be built using new.function(code, globals()). Eventually
we need to automate all of this so that functions themselves can be pickled.
