<<I actually find it odd that we do so badly in examples like that.
It makes me wonder if we do the same thing for C++ code. If we do, and
it's spilling link registers like that, all the time, it must *really*
kill virtual function performance, among other things.

Indeed, one has to react partly that the new allocator looks good, but
partly also that the old one seems surprisingly bad in this case.
