Playing with this a bit, the above change does indeed blackhole the
log message. The question then is how someone can get these actually
outputted the log when they want to. Right now the TCP unit test for
test_connectionLostLogMsg expects textual output to the log. I'm
re-working the test to instead expect the dict with the same values
passed in, but that just ensures the data is properly passed to
log.msg() not that it's going to show up if you want it to.
