If your closure array has a back-pointer from each array element to each 
JS function object, then you can use the GC callback's GC_MARK_END call 
to iterate over the array, calling JS_IsAboutToBeFinalized(cx, funobj) 
on each.

This is what XPConnect does (sorry, my allusion to it in a previous 
message was unclear).
