The =2 case should be some other name, of course. I'd rather
not use the obvious "CP_ACCESS_UNCATEGORIZED" because that
implies "use this if you don't know", when actually the set of
things which cause Uncategorized exceptions is a specific list,
and it's the 'due to a configurable trap' case which is defined
as "all those which aren't defined to cause an Uncategorized
exception". On the other hand I can't come up with a better
name right now...
