OK, just rebooted and took more careful notes. Here's precisely what's happening now.
After rebooting the cp shows 2 green bars. So both modules are running (explorer test shows they work as well). However when cameras are triggered, AI acts funky. I get 2msec makes and always nothing found... ai details for these clips show no modules are being used (just red X's, without the expansion menus to show the models did):

Then I stop and restart ai manually using BI settings. It starts working, but with faces?!

I do not have faces enabled as you can see; unchecked in BI and grey in the cp. This explains now why make times are high. Not sure how to fix this.
[edit: I just tried to see if enabling faces in BI, then disabling faces would change things. When I did this, the control panel did show faces starting and stopping as expected. However, after turning faces off in BI, faces went grey as expected in the cp, but triggers are still showing faces ~80msec. WTF? Seems like BI is frozen with faces enabled... and not sure why 80msec nothing found when the module is greyed out?]
