The deleter takes care of the pointee, but we are talking about the count. I
think.

I still find the

    list< shared_ptr<X> >

hypothetical example where everything needs to use the same custom allocator
somewhat artificial. In "custom allocator" situations I find

    vector< X* >

a somewhat better choice since it has much less overhead. But I may be
wrong. :-)
