Sorry about the confusion here. This patch series can be applied to the next branch. They apply cleanly on [3]. The lifecycle functions are re-introduced in [4], which we could incorporate sooner if useful. I didn't have a consumer for the calls in the original patch series, and so deferred them until there was a caller. I would be interested to understand how the mem_pool would fit your needs, and if it is sufficient or needs modification for your use cases.
