1 year ago UPDATE. Right now a lot of tests pass, but also many fail. Unzip does seem to work.
Here is a simple example illustrating that creating a zip file is broken as before. The size of the entry is wrong.

It fails all tests in the test suite, and trying to use zipfile to make a simple zip file results in a broken empty zip.
I'm extra motivated to fix this so that the asset bundling code for the standard cpython library can run as 100% WASM, rather than having to use python-native.
