Summary: zipimport does not accept nested pure python imports

Initial Comment:
I presume this is a big with zipimport. It occurs when
you have a nested pure python package structure. It
doesn't occcur if there are byte-compiled versions in
the zipped directory.



as pure python zipped directory
===============================

Assume mylib.zip is inserted on the sys.path with the
following
directory structure:

mylib.zip
	mod.py
	p1
		__init__.py
		mod.py
		p2
			__init__.py
			mod.py

C:\TMP>ls
mylib.zip
