Destroys the default loop again (frees all memory and kernel state -etc.). This stops all registered event watchers (by not touching them in -any way whatsoever, although you cannot rely on this :).
+etc.). None of the active event watchers will be stopped in the normal +sense, so e.g.ev_is_active might still return true. It is your
+responsibility to either stop all watchers cleanly yoursef before
+calling this function, or cope with the fact afterwards (which is usually
+the easiest thing, youc na just ignore the watchers and/or free () them
+for example).
