ends).  We may be able to have some implemented for the 4.9 release.
By far the most important aspect of this is defining your pools and their lifetimes properly. If you're not careful, this will end up like the old obstack mess we had in the past.

I don't want to discourage the work, but we need to think carefully and get it right.
