Instead of blocking up the whole test suite when a latch or event was not decremented to its desired value (or not set for an event) we should use a reasonably high value that we use when waiting for those actions to occur and verify that when those wait() functions return that we have reached the desired state and if not either raise an exception or stop further testing.
