But require polling, they dont send Windows messages which is how they are 
normally used in Windows. Its very rare to use non blocking sockets in 
Windows without using Windows messages, unless you are using overlapped I/O.

Yes it is - but forking and block remains the most common way to work under 
Unix for a variety of reasons. It is the "core" method and is not a hack by 
any venture as the original poster claimed.
