Hmm. I don't know. Some tests have timeouts set because they either *do*
take that long or *shouldn't* take as long as the timeout (e.g., those
that might deadlock).

I think, instead, that --min-timeout and --max-timeout options might be
better which allow you to say "this machine is slow; tests may take
longer (max(property, option))" or "this machine is fast, clamp down the
timeout (min(property, option))". Alternatively, a --timeout-scale
option to multiply all timeouts in properties might be better.
