6823609: (se) Selector.select hangs on Windows under load
This is a hang in the Windows select-based Selector that has been
haunting the woods since 1.4.1. This Selector employs a helper thread
per 1023 registered channels. If the number of required helpers
decreases and immediately increases then it possible, under load
conditions, for a redundant helper to poll and finish a cycle instead
of terminating. This can cause the main Selector thread to wakeup
prematurely or to hang because the finished thread count goes
negative. The fix marks redundant threads as zombies so that they
terminate without interference.
