| * 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. |
