[This is a spin-off og bug 412491 comment 8 and later]

Currently XPCNativeMember::Resolve creates a new JS function just to clone it later when used. This creates an extra JSObject+JSFunction pair (8+6 words) to save a JSFunction instance when cloning the function. This extra initial JSObject+JSFunction pair creates long-term live GC things and for short-lived clones the average overhead of the extra JSFunction can be lower then the overhead of the pair.

Thus I suggest to consider skipping the cloning and just call JS_NewFunction as necessary.
