Closing the child causes the main to run, cutting the main breaks execution. This appears to be a problem with any python 3.x installation I have done.

Thanks for the report.

I could not reproduce the problem 1).

As for the problem 2), it seems to be the same problem with
https://www.cygwin.com/ml/cygwin/2020-01/msg00093.html.

I already submitted a patch for that issue:
https://www.cygwin.com/ml/cygwin-patches/2020-q1/msg00010.html.

I confirmed the problem 2) is fixed with this patch.

Please wait for the new cygwin release.
