To get data from a source object, always call "thatSource->getNextFrame()".

Note that the error about "atempting to read more than once" occurs 
if you call "getNextFrame()" on the *same* object a second time, 
before the 'after getting' function from the first call has been 
invoked.  I.e., it's OK to do:

	source->getNextFrame(..., afterGettingFunc, ...);

	void afterGettingFunc(...) {
		source->getNextFrame(...);
	}

but you *cannot* do:

	source->getNextFrame(..., afterGettingFunc, ...);
	source->getNextFrame(...);
