I've only had a sec to look at this, so forgive the guessing...

Your fix seems to work with first-level package modules.  Something is
still off with nested packages though.  If I have package "two" inside
package "one" like so:

+Lib
  +--one/
      +--A.py
      +--__init__.py
      +--two/
          +--B.py
          +--__init__.py

You've solved "from one import A". Definately a step in the right
direction. It doesn't seem to fix "from one.two import B" or
"from one import two".

SyspathArchive.makeEntry only really affects loadFromZipFile in
imp.java.  This makes side-effects unlikely.
