REVISION SUMMARY
  I'm not sure why this only happens with py3, but this error code doesn't map to
  any of the 3 currently being handled, and kills `run-tests.py` before it can run
  any tests when it happens:
  
    OSError: [WinError 10013] An attempt was made to access a socket in a way
    forbidden by its access permissions
  
  The documentation[1] says this can happen if another process is bound to the
  address with exclusive access.  This seems to keep it happy.
