No objection here, but is there something special about this old perl
pmda that makes this widespread cautionary verbiage moot?

       -d   It is absolutely crucial that the performance metrics domain num-
            ber  specified  here  is  unique and consistent.  That is, domain
            should be different for every PMDA on the one host, and the  same
            domain number should be used for the same PMDA on all hosts.

(In this case, 88 happens to be hard-coded into the pmdasystemtap.pl instead
of being supplied as a command line option.)

(If we do it right, it will be useful far beyond stap.)
