All that remains to fully support creation/destruction of weakrefs over multiple mutators is to wrap a critical section around mutator updates to a GC's weakref Hashtable.
Bug 623618 provides the lock-free synchronization necessary for an object's kHasWeakRef GCbit.
The kFlagWeakRefs bit of a GCAlloc's slowFlags requires no synchronization: it is the only bit of slowFlags set outside of a safepoint task, and is only cleared from within a safepoint task.
Note that a synchronization-free path is provided for batch clearing of weakrefs within a collection safepoint task.
