- Use atomic ops both to set and reset async_sent flag - Remove the MinGW atomic ops, since Windows intrinsics are supported - Remone thread-unsafe checks from uv_async_send According to MSDN there are no alignment requirements. We could use InterlockedExchange8, but that's only available on Windows >= 8. This change is intended to make uv_async_send more resilient. It has to be thread-safe, and that means that the handle could just have been closed when uv_async_send was called. This case was previously not handles (there is an inherent race condition). The new model is inspired by the one used on the Unix side, which uses a single fd (or overlapped in this case) to wakeup the loop and then process all pending async handles. This makes handling those edge cases a lot simpler: when the handle is closed it's removed from the handle queue, and then it's not processed at all. As a result of this change, async benchmarks work on Windows where they previously failed with assertions.
