Not at all - the script fragments were merely examples of a general
syntax.  There is no reason that the probes being enabled/disabled
might not belong to an altogether "foreign" facility such as a timer,
or a kprobe, or another process's uprobe.  (This one reason why the
implementation of disableable probes will be a bit tricky.)
