So lets get specific...

On win32 if I open a TCP socket will it will return immediately?  Presumably
then I won't find out the success of failure of the socket open until some
later time when the async open completes?

I'm interested because I have a perl network app and am thinking of
rewriting in ruby, but I have had to already invest quite a lot of time
understanding the peculiarities of sockets under windows and perl...
