ARC/RC also stops the world, hence the typical optimization to 
move the referenced data to a background thread when the 
reference count reaches zero for cleanup, and use of 
deferred/hazardous pointers.

Which when coupled with a couple of other optimizations, it 
becomes hardly indistinguishable from basic tracing GC algorithms.
