Say I have path A, B, & C. The constraints on the diverge node indicate that A & C should be executed simultaneously, but B should not. Then the converge node should wait for A and C to finish, but not care about B as it was not executed by the diverge. Initial attempt was to use Diverge(OR) and Converge(AND). The problem is that the Converge (I think) waits on B indefinitely and so the process exits out with no error message. It looks like n-of-m is kind of what I want, except I have no way to know how many paths the Diverge kicked off. Any thoughts on how this could be done?

A, B, & C could fire in any combination, but always at least one.
