SIGNAL HALT race condition in test-rebind.py
If tor exits due to SIGNAL HALT, before the python subprocess module terminates it, then test-rebind.py can fail with OSError 3 (no such process).
This race condition causes make check failures on my laptop running Windows Subsystem for Linux. It could potentially cause CI failures on busy machines.
I have a patch that rewrites test-rebind.py to be more reliable.
