/**
* 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.
