That deserves more research. I'm not sure I believe we understand exactly
what goes on in each case -- perhaps our zip reading code isn't as
efficient as it could be? It would also be interesting to compare different
platforms.

And it's probably premature. (Unless you already have a prototype and it
shows a solid speedup.)
