tjanczuk/iisnode — Issue #110: perf: avoid context switches for synchronously completed async IO calls

ReadFile and WriteFile against a handle associated with an IO completion port normally post a completion packet therefore requiring a thread switch to complete the operation. This is to configure the handle such that it does not post completion packets to IO completion port for synchronously completed IO.
