SingleStateExecutor

class SingleStateExecutor extends ProcessExecutor[Int] with SimplePiObservable[Int]

Executes any PiProcess asynchronously. Only holds a single state, so can only execute one workflow at a time.

Running a second workflow after one has finished executing can be risky because promises/futures from the first workflow can trigger changes on the state!
