Again, all these containers that will use the same cache_alloc won't
have to worry about how they implement the container. So I just think
this is a good way to abstract things.

Yeah that's because I had issues with the rebind stuff with other
containers (stack, queue, ...). Only lists don't suffer from this
problem in my system headers so I'm using them for the benchmark example
(why do we use rebind when we have template templates anyway?).

But please stay tuned, I'll do a full benchmark once I fix that.
