Actually, what's really interesting is the new registered IO facilities in Windows 8/2012. The Microsoft recommendation for achieving the ultimate performance (least amount of jitter, lowest latency, highest throughput) is to do something like this: while (1) { if (!DequeueCompletionRequests(...)) { YieldProcessor(); continue; } else { /* Handle requests */ } }

Does Microsoft change their recommendations every couple of years? :)
