Correct.

We may also want to add some support for mgr:mem page and stuff, but
that's extra bonus.

c?

All of the above (both groups) provide malloc type interface, which
means they drop right in. Just need to be a little careful with our use
of mallinfo. From what I know we only use malloc, calloc, free and
mallinfo.

any plugins or third-party libraries also need the same concern if we
use a malloc implementation not fully providing the same functions as
the system malloc.
