I have some code which does so for a set of processes by calling process info for each process as you do. But, I retry until the processes reach a fixpoint in reduction count and status. This is not entirely safe either, but it is better than just looking at the state. And it works for some of my Erlang QuickCheck test cases when considering if they are stable.
