Yes, Gordon and Alex have agreed with this, that async methods are handled in different threads.
But the original poster's concern was regarding developer code within the AVM: "If A' starts executing before B', will it run to completion before B' starts executing, or could their execution be interleaved?" We are just reassuring the op that no, this (interleaving) will not occur.

But the ActionScript Virtual Machine executes in only one of them. According to the Flash Player engineers that I have spoken to, some ActionScript method calls are handed off to other threads, for example URLLoader.load(). It would be helpful to read a more detailed and complete explanation of the Flash Player's threading model, and how functionality exposed by ActionScript VM is scheduled. Mike
