If you spend a few 0.1ths of a ms every 10 ms on reference counting, smart
pointers or passing around other meta data it's the just as bad. I have no
data but even worse would be, as I expect is true, if non GC apps end up
being architected different to make memory management easier (if so, you
can bet money it won't be faster as result).
