If the system is POSIX compliant, this should not be an issue because
SO_REUSEADDR applies to whether the listening application can re-use
the socket in the TIME_WAIT state (that which has been closed
already). This is important for efficiency reasons, although can
definitely be dangerous in systems where the networking stack doesn't
clean up properly.

If this is a problem only in Windows then we should have a special
compiler flag that turns it off.
