Yes, or perhaps just smp_processor_id() if that were more general and

Exactly.  Feel free to submit a patch for one or both of these
additions to the appropriate .stp files, and brief documentation in
src/stapfuncs.5.  I can commit them for you, or if you forsee becoming

That reminds me.  Time to add a GPL header to the tapset files.
