I'm curious to hear more about this.
An example is when you have a huge graph and the root reaches it count
== 0.
The time taken into a cascading deletes of the whole structure is
similar to a stop-the-world GC pause.

That's a generic example, but ARC proponents steadfastly maintain that it
doesn't happen often enough in practice to be relevant. Mr. Teoh's
examples of it would be most helpful. And there is more than one way ARC
can go horribly wrong, like cyclic references inside a huge graph.
Wouldn't THAT be fun! :-) I could design a huge graph that never gets
freed in ARC in my sleep, I've built them before without trying hard in
C#, most of the time quite by accident, but not always...
