Re: seda for dummy questions: events

(I will answer some of my own questions for benefit of archive)

true
in init(), use
config.getManager().getSignalMgr().register(new StagesInitializedSignal(),
config.getStage().getSink());

You can't right now, but if the SignalMgrIf api is updated to reflect the implementation's "public
void trigger(SignalIf)", then you would use it.

Signal's getClass() object is used (as by the Hastable keys contract, that .equals() and
.hashcode(), that means ==)

implement SignalIf marker interface and hope SignalMgrIf.trigger(SignalIf) get's added to the api 
soon, or don't try...
