Solution: Provide poll() for Windows as well. This is a build option that defaults to off as the resulting binary will only run on Windows Vista or newer. This is not tested with alternative Winsock service providers like VMCI, but the documentation for WSAPoll does not mention limitations. On my local machine, throughput improves by ~10 % (20 simultaneous remote_thr workes to one local_thr, 10 byte messages), while latency improves by ~30 % (measured with remote/local_lat).
