Justification (very roughly): the size of a right adjoining subtree can at most
be equal to the left adjoining sub-tree. This entails a logarithmic number of
re-examinations from the right adjoining tree.
(TBD check how Hopcroft's main argument is phrased)
The parent lists are bounded by the maximal arity of functions.
