Pool segment backend

My understanding is currently segments are stored in std::vectors.

If I wanted to create a base_collection using a pool instead of a vector, would I just have to create a new segment_backend using a pool class for storage?

It seems using a pool backend would avoid the problem of vector memory reallocation causing object pointers and iterators to become invalid.

Motivation: I want to make object creation and deletion cheaper while retaining a polymorphic collection. Truly pie in the sky. =)
