Yes. MSDN: The select function returns the total number of socket handles that are ready and contained in the fdset structures, zero if the time limit expired, or SOCKETERROR if an error occurred. If the return value is SOCKETERROR, WSAGetLastError can be used to retrieve a specific error code.

Argh! So select() has never returned proper return values on Windows. :-(

Thanks for fixing this. Are you gonna fix it in 2.2.2 as well as 2.3?
