I eliminated TE from the project, and there has been no motorboating after 3 hours of being idle.  I hope that is the answer.  CW if you're listening in, I hope you take note and fix this minor problem.  From the comments that I've read, TE seems to be popular, and I would like to have this option available without the hassle.  I'll send in a bug report, anyway.
