Is there a debug switch to get a stack trace? I tend to think they're useful...

Yep, I want to refactor the logging. The original way was preserved mostly intact for the 1.0 release, and I think that was a mistake. Maybe I can set aside some time soon to put together a 2.0 to change the logging. I will leave this open until we can resolve that.
