Yes, I'm quite strict right now and IMHO in the current tests, that's
the only sensible order of events.  But of course if it turns out that
with some notification backend we can't achieve that guarantee, it'll be
no problem to relax the assertions a bit.

Yes, you are right.  I always executed the test interactively and now
tried running them from the command line.  Indeed, that's way faster.
