Comment (by Vort):
Here is the test for WSAIoctl/setsockopt performance.
`BwTest.exe -s -u -t` was started on Windows 7 computer with real 100
Mbit/s and 1 ms link.
Yet again, ISB was equal to 65536 all time of the test.
Result: WSAIoctl and setsockopt functions uses 0.25% of CPU resources,
comparing to other WS2_32 functions.
