This is an interesting idea. It would be nice to have, even as an
option. If somebody wants to step up, provide an implementation and
volunteer to maintain it, I'd be much more interested.

The persistant allocator in POST++ is also interesting. 

The more options, the better.

This is definitely the place. 

I'd suggest coming up with a concrete proposal, perhaps posting a design
document or something on this list and soliciting feedback for the
implementation.
