Well, yes and no. I think it's still useful for the test to verify it
can complete. Otherwise it might have hit an undetected deadlock and
we falsely report the test passed.
What we could do is pass in test_length and fail any test which uses
that value and doesn't complete in test_length+2 seconds (or +3 or
+5 or whatever stetson-harrison value is reasonable. let's solve the
halting problem some other day). Alternatively, we could fail all fast
tests which don't complete in the grace time (maybe if the test sets
``timeout'', we need to take it into account and wait until timeout to
fail the test).
