You should not have to do that, but the GC must be run after the root is 
removed.  If such a GC does not collected the object, then it must be 
rooted otherwise, or connected via one or more properties to a rooted 
object.  You can use GC_MARK_DEBUG and js_LiveThingToFind to discover 
how it is being marked, if it is not GC'd after the JS_RemoveRoot call.
