    is it possible to delay such a hook until, say flush_old_exec?  or perhaps
    this is enough justification for moving prepare_binprm to after the
    copy_strings since set_security should have enough info to label
    accurately.  hmm, i suppose the capabilities pieces that are in
    set_security don't rely on being inside of prepare_binprm, so we could
    conceivably just move that hook.  i'll stop thinking out loud now... ;-)
    
    i'd rather not introduce new hooks if we can solve the problem with
    existing hooks.
    
    thanks,
