 /**
  * Tries to acquire a lock.
  *
  * If acquiring a lock fails, it uses a blocking connection waiting for the current
  * client holding the lock to free it. If the other client crashes or doesn't free the lock, the returned
  * promise will fail, because once having entered the blocking mode, it doesn't try to aquire a lock until
  * another client frees the current lock. It can't react to key expires. You can call this method once again
  * if you absolutely need it, but usually, it should only be required if another client misbehaves or crashes,
  * which is clearly a bug then.
  *
  * @param string $id specific lock ID (every lock has its own ID).
  * @param string $token unique token (only has to be unique within other locking attempts with the same lock ID).
  * @return Promise promise fails if lock couldn't be acquired, otherwise resolves to true.
