Comment (by rcurtin):

 r14120 makes the bound a little tighter, giving

  * jl-constructed cover tree, jl dual-tree traversal: 83962
  * jl-constructed cover tree, mlpack dual-tree traversal: 98201 (was
 111225)
  * mlpack-constructed cover tree, mlpack dual-tree traversal: 112039 (was
 189628)

 The parent-child prune has not been implemented safely yet.
