Nice, but that completely missed the point of my question. I know this
wouldn't be a problem in this exact case. The question is: when is the GC
free to free data passed into a function's arguments. Will that function
hold on to all data passed in through arguments until the execution of the
function terminates? If so is there a way to trigger garbage collection of
unneeded argument data before the end of the function's execution?
