A Memory pool is indeed that. The exact nature depends on the mempool
implementation in question (which has changed over time), and in 3.0
will be somewhat dynamic, allowing for both slab allocators and simple
os caching pools.

However, we do get folk asking this fairly often, and I'm seriously
considering removing the configure option completely.
