I can specify here a bit. >From my recent testing with orc and arc, you won't get any memory leaks under >ORC, but you _will_ get memory leaks under ARC - so says address sanitizer >(that's the most recent issue I opened on chronos). I therefore assume there's cycles _somewhere_ since the cycle collector of ORC is the only meaningful difference I could think of, but can't really tell where - The stacktraces I left in the issue weren't particularly enlightening either.
