Possible race condition opening SOCKS Port in test_rebind.py
test_rebind.py failed in master because the SOCKSPort wasn't open when the python script tried to connect: https://travis-ci.org/torproject/tor/builds/448008717
When we merge legacy/trac#27968 (moved), we'll get better debugging. But we should also print all the tor logs to the console, particularly when there is a failure.
And we should print the test_rebind.py logs with timestamps.
