The probe's sample plumbing leaves the gate module (the gate never kills; the probe may kill
its own hung child). The counter path is one exported constant passed to the script as
-Util3dPath, the script reports how many 3D engine counters resolved, and a child that is
alive but silent for 3 intervals is killed and respawned.
