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