Change subject: core: do not ping too often ...................................................................... core: do not ping too often Code has a bug causing polling (with FutureVDSCommandType.Poll / ping verb) too bursty when host is responding fast. Changes: 1. method waitBetweenPolls is moved from end of method to the start. When wait is needed, it's the first thing which is done. 2. field lastTimeBeforePoll is introduced. After waiting this field is set with current time. In next execution, waitBetweenPolls will wait if requested POLLING_BREAK is not met. 3. in waitBetweenPolls while is introduced, because Thread.sleep does not guarantee to wait for requested time period, actually it may sometimes return way sooner than that (see comment in method). Not that important changes: 4. extracted reading value from task / handling timeouts to single method for code clarity 5. added trace logging for next time this class misbehaves.
