The only way I can see that we'd catch this (by testing external logs)
in the current qa setup is
There are no specific tests to test out external logs (there is 044 but
it requires the env vars set anyway) such as using a loop back device
for the log. Perhaps we should do this.
I should check that our QA group are setting the vars in some runs.
