Implementing grouping that really works is quite hard.
What about when groups are nested? This can go on indefinitely, so you

You have no guarantee that a method like -initWithContentsOfFile: is not going
to add many allocations to the autorelease pool (which probably exists at your
top runloop). In my code, in places that sit in tight processing loops, I've
had to create an autorelease pool at the top of the loop
