[issue45055] Fresh build on Windows fails the first time for zlib.c

[Steve Dower]

Steve Dower <steve.dower at python.org> added the comment:

I use git worktree as well (it's great for backporting - I have all the release branches checked out all the time), but it likely means that you are regularly downloading and extracting these files.

So whatever app is keeping the file handle open is probably doing it reliably for one of the files, which is why you'll hit it each time. Once it's been copied into place, you won't see it again. And once we have the retry logic in the script then you won't see it the first time either.

This should be an easy project, though not trivial to test.
