Are you saying that the method script itself might manipulate the
service, or that the system admin might do it?  SMF has ways to
prevent multiple instances of the method from running and to make
enable and disable requests synchronous.  Can you do what you want
within SMF, or does the method script had to do all the process
manipulation?
