    Cast users of JS_EnterLocalRootScope
    
    In Xulrunner 1.9.3, this is now a no-op.  See
    upstream bug: https://bugzilla.mozilla.org/show_bug.cgi?id=519949
    
    Now in theory, we should be checking the return value and handling
    that.  I wrote a nontrivial patch to do this, but decided it
    wasn't worth it, since in newer xulrunners it's just pointless
    code spaghetti, and in older, it's not like we're really
    going to go OOM in reality.
