I've just joined the list and have only poked about drizzle a bit, so
please don't beat me up too much.

Examine HOARD allocator
Is HOARD already used by Drizzle?
One other worth investigating that has a lot of miles on it already
(especially in terms of scaling to lots of cores/threads and handling
cache alignment) is libumem. It too is portable (ported from
OpenSolaris by the OmniTI guys) and is also a dropin replacement for
standard allocators. It's newer than HOARD in that it has only been
available in userspace since Solaris 9, but it's a port of the original
multithreaded slab allocator which has been around since the mid '90s.
In addition to it's speed/concurrency, it has a bunch of things to
simplify development.
Two quick references:

Anyway, if you're going to study baseline/HOARD, it could be worth
looking at baseline/HOARD/libumem.
