Or we could implement `test_atexit` (similar to `test_when_finished`, but
to be executed at `test_done` time). I guess that's what the p4 and daemon
tests really needed to begin with (and probably also the apache2-using
tests).

Now that you mention it... I agree. This is getting long.
In the short run, I have two things to consider, though: I want to make
this work first, then think about introducing a layer of abstraction, and
I want to go on vacation tomorrow.
So I agree that this is something to be considered in the long run, i.e.
not right now ;-)
