Merge PR #26: (Win32) Remove delay_socket

My hack came from many years ago, but still it's unlike me to miss
something like so basic as Sleep().  So I suspect there was A Reason
I did it this way (despite the contrite comment).

But I have no way to test it at this point, so I'm just gonna merge it
in.
