Suspend/Resume state machine

[vstirbu]

This feature would enable a state machine object to be suspended. Ideally the state machine should have a suspend method that returns an object containing the current state as well as the internal state.

A suspended state machine can be resumed using the object returned by the suspend method.

Curious about what is the use case for this feature.

Basically, I want the application domain state to be saved on each successful state change so that I can restore the state machine object later on, in case the process/hardware crashes. So, I'm looking for an enabler for high availability/fault tolerance.

Of course this can be done in do it yourself fashion but I want to see if we can identify a pattern here. Maybe the suspend is not a good name but the intent is to have something that formalises capturing the current state and the object properties that are essential to recreate the state later.
