Can I ask why Zope needs it's own api for this and we don't just use
pkg_resources?  Loading files from arbitrary zip files is handled by
python's builtin zip api, no?  The rest appropriate stuff we should be
able to get from pkg_resources.

If pkg_resources has obvious fallacies, perhaps we should communicate
with the author to address these?
