> There are a couple of issues:
> 1. `Selector.determineHandlingOrder()` currently doesn't clear selection keys when keys are shuffled. This can result in select returning zero even when there are ready keys, resulting in a tight loop of polls with no keys processed.
> 2. The test expects `Selector.isOutOfMemory()` to be set in a poll that waits only for 10ms. This is expecting two reads from two connections to be processed within 10ms of each other, which may not always be the case.
> Error:
