If you write code in a way that does not create much cycles you 
don't have to call the GC at all. So getting the GC out of the 
implicit allocations the language make might be the most 
important thing, but how much memory is wasted over an hour that 
way?

A game should perhaps run for 1 hour without a hiccup, ARC might 
be good enough if RC collect 98% of all garbage.

A real time audio application should run for 12 hours without a 
hiccup… you probably want a GC free audio callback.

A real time server that monitors some vital resource should run 
for hours without a hiccup... You either want a real time GC or 
no GC.

Different scenarios have different needs.
