- tasks are still enqueued without reading the clock - in order to be resilient against timer thread over-sleeping the tasks are passed to the timer thread using an AbstractNodeQueue and the wheel itself is now private to the timer thread - reuse queue Nodes along the way to minimize allocation costs The problem with the old implementation was that the timer thread could sleep too long, then wake up and run multiple buckets in quick succession. Tasks enqueued just before that event could then get executed basically immediately, i.e. before their allotted time. |
