I believe the participants consisted of Thomas Wouters, Greg Smith, Eric
Snow, Nick Coghlan, and myself. In the end I think the general consensus
for long-term maintenance was to write the minimal amount of code required
that could read zip files and then write all of the import-related code on
top of that. Basically the idea of freezing zipfile seemed messy since it
has a ton of dependencies and baggage that simply isn't needed to replace
zipimport.

I vaguely remember people suggesting writing the minimal zip reading code
in C but I can't remember why since we have I/O access in importlib through
_io and thus it's really just the pulling apart of the zip file to get at
the files to import and thus should be doable in pure Python.
