Initializing to the state manually as below seems fine. What such
initialization will not do, however, is cause the execution of the
<onentry> of said state, as the state machine is already considered to
be in that state. So, in the original example below, if "STATE_START"
is that persisted state which is restored the <oentry> and thereby the
contained <send> will not be executed.
I don't see anything unexpected in the EventDispatcher implementation.
