Handle the case where gettimeofday() goes backwards or returns the same value
twice; it could cause division by zero in the unit test framework.
(We already had one fix for this in place, but it was incomplete.)

This could in theory happen on any system, since there are few guarantees
about gettimeofday(), but seems to only happen in practice on GNU/Hurd, where
gettimeofday() is cached and only updated ever so often.
