Also, if some actor somewhere does do something extremely time consuming

some effect -- that is, it's indentation changes when pressed -- however,
it does not interrupt the processing. This behavior could be considered a
but itself. Either the stop button needs to be disabled until it can do
something useful, or it should stop the workflow regardless of its
execution state.
Every Director has a method isStopRequested().
A long running initialize() method should just call this method
and abort if it returns true...
I would be circumspect about adding additional phases.
It could significantly increase the complexity for actor writers.
