Hi Daniel,

I have not forgot the issue, I can replicate the issue and
running as

$ PYTHONUNBUFFERED=1 PYTHONVERBOSE=1 pip3 install --force 

it goes a bit further, but at the end stop again

It seems some type of race on 3.9.18 (both -1 and -2, so irrelevant on 
my simple patch trial)

I will see if 3.9.17 has the same issue and after that bisecting until I 
find the upstream change that has problem on Cygwin.

Thanks again for the test case
