If we are to support non static NUMA bindings, the predicate method is itself easier to restore than the code we now remove. If we remove it in this fix, we can later easier see the context of _why_ the predicate was removed, and _what_ it was used for. It will be easier to follow version control history. If we have no non-gc users of this method, I think we can see it as effecting gc only.
