/**
 * 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.
