Well, I did that. No differences again:
non-rbtree real 8m57.498s user 7m49.490s sys 0m48.121s
rbtree real 8m57.650s user 7m50.497s sys 0m48.430s
hmmm.. this is the second real world figure, and while the difference
is absolutely tiny, the rbtree version is once again a slightly slower.
.3 seconds isn't much over nearly 8 minutes, but it is something.
i think the rbtree code isn't worth while. i'm certainly not convinced.
