Comment (by anonymous):

 I don't like the idea of making the address null on all platforms. In UNIX
 MAP_FAILED is not NULL and I don't think I should add a branch in the
 inline get_address to convert map_failed to null, confusing UNIX users.
 I've committed another change, creating an additional invalid_address()
 static function that returns a portable invalid address constant (0 in
 windows, MAP_FAILED in unix). Let me know if you think this can be enough
 to close the bug.
