Great timing!  Serhiy’s rewrite of zipimport in Python has just landed in 3.8, although it doesn’t use zipfile.  What’s in git now is a pretty straightforward translation from the original C, so it could use some clean ups (and I think Serhiy is planning that).  So the problem you describe should be easier to fix now in 3.8.  It would be interesting to see if we can squeeze more performance and better behavior out of it now that it’s in Python.
