IIRC, the attached patch is very much not correct, and that is why it has not 
been committed.  Just because it is one line, doesn't mean it is safe or 
correct.  :)  Anyway, we should look again to be sure ...

I looked at this issue with oej, and we identified clear issues with NOTIFY 
handling in the case where the relevant hint has multiple devices associated 
with it.  We discussed ways to fix it, and he indicated that he wanted to work 
on the fix.  Since he wanted to do it, I haven't touched it, since.

However, in case someone else wants to look at it, I will try to spend some time 
writing down the details of what needs to be addressed.
