…xt in submit Bug mitchellh#209: kqueue tick(0) EV_DELETE flush - Changed early exit condition from 'if (wait == 0) break' to 'if (wait == 0 and changes == 0) break' so pending EV_DELETE kevent changes from the event-processing loop are flushed before tick(0) returns. Bug mitchellh#170: rearm state correction - When a non-kqueue completion (close, shutdown, threadpool fallback) returns .rearm, set flags.state to .adding before pushing to the submissions queue. Previously .dead state caused submit() to route through stop_completion (cancel) instead of start() (resubmit). Issue mitchellh#169: defensive next-pointer clear in submit() - Explicitly clear c.next before push to completions queue when processing kevent-returned events in submit(). This prevents an assertion failure if a completion is present in multiple queues concurrently (race condition).
