Thanks for the pointer, I discussed this issue a few times without actually
ever reading those lines, I admit.

Yes, C++0x is different, much better, with the new scoped allocator model,
which is still slightly in flux. Just in case you didn't notice already, C++0x
will also include answers to "580. unused allocator members", and "635. domain
of allocator::address", which Howard filed at the same time of that change to
our std::list. And also "431. Swapping containers with unequal allocators", by
the way, which, if I'm not mistaken we already implement withing the "old"
C++03 allocator model, per some other exchanges with Howard.
