3382Libev assumes not only that all watcher pointers have the same internal
3383structure (guaranteed by POSIX but not by ISO C for example), but it also
3384assumes that the same (machine) code can be used to call any watcher
3385callback: The watcher callbacks have different type signatures, but libev
3386calls them using an C<ev_watcher *> internally.
