A TimeLimiter implementation which actually does not attempt to limit time at all. This may be desirable to use in some unit tests. More importantly, attempting to debug a call which is time-limited would be extremely annoying, so this gives you a time-limiter you can easily swap in for your real time-limiter while you're debugging.
