Code review comment for lp:~mbp/rabbitfixture/rabbit-startup

The log is put into a temporary directory that is ordinarily erased
during fixture clean-up. At the moment fixture clean-ups are not run
if setUp() raises an exception, but, as Rob says, clean-ups should
really be run. When python-fixtures adopts that behaviour, telling the
user the location of the log file will be pointless because it will
have been erased by the time they see the message.
