Brian is running into 
https://bugzilla.mozilla.org/show_bug.cgi?id=215173 -- the APIs and 
underlying code have design flaws that prevent you from extending the 
set of built-in errors-as-exceptions.  That's something I would like to 
fix, but I don't have time.  Perhaps someone else will take that bug -- 
I'll give advice and review.
