David Chisnall	336d8a828c	Fix test failure. This bug is also present in the original version: When removing a WeakRef from the map, we use its obj field to find the key, but the obj field has already been zeroed by this point and so we end up leaving dangling pointers in the map.	7 years ago

David Chisnall	3f38f691af	Rework ARC code as C++. Move the weak references hash table to use a well-tested third-party implementation instead of the hand-rolled version.	7 years ago
