I'm getting an error with WSARecvFrom in nativeBytesAvailable() and I
don't know why. The number of bytes obtained is correct and the test
works for 2 bytes, so let's use that.
The Windows nativeBytesAvailable() function has a comment saying that
WSAIoctl sometimes indicates 1 byte available when there's a pending
error notification, so that function proceeds to do a WSARecvFrom to
peek the number of bytes. Somehow that function in this test is getting
a SOCKET_ERROR I can't explain.
