Me not either. I did point out that it doesn't fix the problem, only
the impact. Fixing the dt unittest code would have been easy enough,
but I wasn't sure how to properly address the problem in the dt overlay
code, and I was concerned that other code might be affected as well,
so I gave up trying and settled on error handling.

Looks like Frank is going to provide a proper fix, so we should be covered.

Thanks,
Guenter
