That means classes that need cleanup (either directly or by

So essentially, any class with a dtor needs reference counting?
How does one clean up a cycle of them?
Yeah, what he said. This has me very worried. Making cycles is
actually incredibly easy. Any "inteligently" implemented
"node-based" data structure, implemented with classes, such as a
linked list, a tree or a graph, is virtually guaranteed to have a
cycle somewhere...
*Or*
is the idea that reference counting only works for finalization,
but the memory is still managed by the GC? In that case, the
destructors would leak, but the memory still be released?
That's still bad, of course, but not "as" bad...
