Ah, I see.  So staprun really does magically know about being setuid, not
just "privilege works".  In that case, to run under sudo it would still
take a little wrapper (to call setresuid and exec staprun) that is hard to
script.  But wait, the mother of all bad scripting solutions can handle it!

I pushed some new code.
