tests: run with PYTHONHASHSEED=random Python set and dict iteration order is in principle undefined but usually 'quite stable'. Setting PYTHONHASHSEED=random will make the iteration order more random in Python 2.6.8 and 2.7.3 and where it has been backported. This can thus help spot dependencies on undefined behaviour and prevent future problems. [ original upstream message ]
