   - `retryTimeMillis` -> `pollingInterval` -- and it is now only used for expired locks, other wise pub/sub is used with released locks
   - `failAfterMillis` -> `failAfter`

-- `timeout` and `pollingInterval` have defaults. Locks are now allowed to lock indefinitely (except with work around mentioned in "Lock Options" section above).
