Note that SO_REUSEPORT is set in addition to SO_REUSEADDR, so we're actually
mapping Windows SO_REUSEADDR to the combination. It's still not correct because
on Windows SO_REUSEADDR doesn't have to be set on the first socket while
SO_REUSEPORT must be set on all sockets on OSX and Linux.

So the app has to set SO_REUSEADDR on all sockets, which might be the case if
it was written with portability in mind, for example. 

Linux introduced SO_REUSEPORT in 3.9 with slightly different semantics but it
looks like it can be used to improve compatibility in the same way as on OSX.
