Here's the fix we're applying in pyrun to make -m imports work at least for
top-level modules:

This makes runpy work for top-level frozen modules, but it's really only
partial solution, since pkgutil would need to get such support in more places.
We also found that for some reason, runpy/pkgutil does not work for frozen
package imports, e.g. wsgiref.util. The reasons for this appear to be deeper
than just in the pkgutil module. We don't have a solution for this yet. It is
also not clear whether the problem still exists in Python 3.x. The __path__
attribute of frozen modules was changed in 3.0 to be a list like for all other
modules, however, applying that change to 2.x lets runpy/pkgutil fail
altogether (not even the above fix works anymore).
