(* Checks behavior of unification with respect to the size of evar instances *)
(* Expected time < 2.00s *)
(* Note that the exact example chosen is not important as soon as it
involves a few of each part of the unification algorithme (and especially
evar-evar unification and evar-term instantiation) *)
(* In 8.2, the example was in O(n^3) in the number of section variables;
From current commit it is in O(n^2) *)
