Hmm... mark-sweep collectors, provided you have a good allocator, should
be able to outperform ref-counting smart pointers, particularly in a
multi-threaded environment. I haven't looked at this particular GC, but
I know of others which handedly kick smart pointers all over the place,
at least for the common case.
