New in version 1.4: two calls to new_handle(x) are guaranteed to return cdata objects with different void * values, even with the same x. This is a useful feature that avoids issues with unexpected duplicates in the following trick: if you need to keep alive the “handle” until explicitly asked to free it, but don’t have a natural Python-side place to attach it to, then the easiest is to add() it to a global set. It can later be removed from the set by global_set.discard(p), with p any cdata object whose void * value compares equal.
