This result is influenced by zipimport fseek-ing for every file in the
imported zip and fseek flushing buffers in Microsoft's CRT
implementation. There's a patch which avoids the seek in
http://bugs.python.org/issue8745. Reviews welcome!

With that patch the time taken to import is half of the current state
of things so according to your test that would make zipped and non
zipped configurations roughly equally fast.
