concretization: fix transient hang in python 3.5

Browse source 
Bug relates to the interplay between:
1. random dict orders in python 3.5
2. bugfix in initial implementation of stacks for `_concretize_dependencies`
   when `self._dependencies` is empty
3. bug in coconcretization algorithm computation of split specs

Result was transient hang in coconcretization.
Fixed #3 (bug in coconcretization) to resolve.
