   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.
