Provides support for locating and running Python scripts using the Python
module namespace instead of the native filesystem.
This allows Python code to play nicely with non-filesystem based PEP 302
importers when locating support scripts as well as when importing modules.

Note that the executed module will have full access to the
__main__ namespace. If this is not desirable, the run_module()
function should be used to run the module code in a fresh namespace.
At the very least, these variables in __main__ will be overwritten:
