The function is not doing anything on Windows because:

1. Windows' connects don't need to be "verified" with this function.

2. When using many threads on windows, this function call becomes a bottle-
   neck. It takes nearly all CPU time, as discussed and researched by Andrew
   Fuller back in October 2003.

So, I take it we can use getsockopt() to get the error in case of failure, but
I think we should avoid calling it just to verify the connect as is needed on
non-windows platforms.
