From looking at a lot of the qDebug's I've littered around my data engine 
and applet, it seems that setData's are coalesced, or at least are 
sometimes. A few in a row may result in a single dataUpdated, though 
sometimes it may result in a few dataUpdated's.

But a lot of the time, many of my setData's just aren't triggering an update 
in the applet at all. Or at least setData("source", "key", value) version 
doesn't seem to behave as I expected it to.
