Description

Sometimes the test suite has failures like: 

Traceback (most recent call last):
  File "/tmp/tahoe-lafs.tox/py27-coverage/lib/python2.7/site-packages/twisted/internet/defer.py", line 122, in execute
    result = callable(*args, **kw)
  File "/tmp/tahoe-lafs.tox/py27-coverage/lib/python2.7/site-packages/twisted/internet/posixbase.py", line 495, in listenTCP
    p.startListening()
  File "/tmp/tahoe-lafs.tox/py27-coverage/lib/python2.7/site-packages/twisted/internet/tcp.py", line 1363, in startListening
    raise CannotListenError(self.interface, self.port, le)
twisted.internet.error.CannotListenError: Couldn't listen on any:38205: [Errno 98] Address already in use.

This shows that some TCP server has failed to start because EADDRINUSE. This makes debugging such failures infuriating.
