- generic/nsf.c: A tentative patch for two (related) misbehaviors of alias methods binding objects (4 MEM_COUNT scores in contains.test). The in-code comments include synthetic examples and some hints. While the first case (repetitive alias registrations of identical objects) is rather obvious, the second turned out tricky: When aliasing a nested (!) object, NSDeleteChild() won't clean up the alias object references properly. The current patch requires a thorough review ... for now, the patch closes the leaks.
