data so their isn't an opportunity for gaps over overruns (init_data).
Start some preliminary tweaking of policy class numbers.  It looks
like I can easily drop the default connection count to '4' and
still hit the throttles.  Did some experiments running pipeline
deeper which was mostly fine for textures but tended to slow
meshes.  Reason uncertain but a depth of '5' seems generally healthy
for mesh.  I had one run of 52.6S with a theoretical minimum of 51.2S.
That's as good as I've ever seen.
