It was a bug, if 2 objects registered the same synchronous event it got
delivered twice. Fixed now. I also restructered the code, it should be a
lot more clear now, albeit a little slower.

I think the console should use async events, read the documention in
EventDistributer.hh about the pollSyncEvents() method.
