Sure, not *routinely*. It'd be a special case where it's not
specifically a destructor, and its job is to break a reference cycle.
For instance, you might have a close() method that clears out a bunch
of references, which will then allow everything to get cleaned up
promptly. Or (a very common case for me) a callback saying "remote end
is gone" (eg on a socket) might wipe out the callbacks, thus removing
their refloops.
