I admit that I've lost the context in this discussion.  I'm CC'ing
Stefan in the hope he could tell whether we do or don't have a problem
here; if Stefan is unable to do that, either, we will unfortunately
have to get back to the beginning and explain what kind of problems
the current behavior causes.  Because in general what Jimmy described
in the original report sounds the expected behavior to me.
