I actually started on one earlier, but what would it check? We already
die() in this case. Should we be grepping for the message? It seems more
likely to me that we would change the message and cause a false positive
than that there would be an actual regression.

What I think might be more interesting is if die("BUG") could learn to
exit with some error code that the test suite considered invalid. Like
calling abort(), which would kill us with SIGABRT and cause
test_must_fail to complain.

On many systems that would also generate a coredump. Which is handy
sometimes, but I wonder if it would be inconvenient for others. I guess
that is no different than what a raised assert() would do.

But if we were to do that, then the test could easily demonstrate that
we expect a clean die().
