> Remove the busy wait from AtomicSafeInitializer.get().
> Also ensure waiting threads do not wait indefinitely after initialize() throws an exception,
instead throwing the same exception, re-wrapped, for each requester.
> Brought the unit tests up to 100% coverage on AtomicSafeInitializer. Eliminated race
condition on verifying at least one thread waiting for initialize() to complete in another
thread.
