[issue21822] KeyboardInterrupt during Thread.join hangs that Thread

[Paul Goins]

Paul Goins <paul.d.goins at intel.com> added the comment:

I've confirmed this issue on Windows.  Attached is an SSCCE which seems to reliably reproduce the issue in a Windows environment.

Long story short: if a KeyboardInterrupt occurs during Thread.join(), there's a good chance that Thread._is_stopped never gets set.
