On windows, send and recv use overlapped I/O. The
io_service::run() function waits on GetQueuedCompletionStatus()
so that it gets the result of these asynchronous operations
directly. What I mean is that asynchronous connect operations
currently require an additional background thread to wait on
select(). Using ConnectEx will remove this need.
