------------------------------+--------------------------------
 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.
