I was writing a TAP test to reproduce a crash recovery issue and used
parts of 041_checkpoint_at_promote.pl. Unfortunately, my test wasn't
waiting for the desired message to appear in the log. I then realized
there was a mistake in log_contains(), which I had copied from the
existing test. After testing 041_checkpoint_at_promote.pl multiple
times to see if it worked as expected, I noticed differences in some
iterations.
