If you resolve an INS IOR, the repository ID is not set.  This causes the orb
to check with the remote orb *every* time an _is_a() or _narrow() is called on
that object.  If the repository ID is set, this wouldn't be necessary.  I
believe this can be fixed TAO_GIOP_Invocation::location_forward.

I'll take a look at this.

Sorry it took me so long to look at this one.  This is not a bug, there is no
way to specify the type_hint for URL-style object references.  So the client ORB
must use _is_a().  This shouldn't be a problem in general because URL-style
object references are intended for bootstrapping a few objects only.
If the application really wants to avoid the _is_a() call then a possible
workaround is to use _unchecked_narrow().
