That's what I did.  But, looking at the import machinery, the newly imported
object is added in to it's parent object with '_setObject', which then goes
and calls "self.manage_afterAdd()", which then goes down into all of the
subobjects and calls that.  That's probably the right thing, but it is
what's causing the double cataloging, regardless of how the item is
cataloged.  Catalog*Aware objects call into the catalog during
manage_afterAdd, and I'm sure that the same thing is happening to my "WHEN
OBJECT ADDED..." triggers as well.

*sigh*.

I've got a few quarter assed solutions in my head, but I don't like any of
them.  Waaa.
