I'd like to suggest here, if you are giving this code a facelift, that on Windows you use VirtualAlloc and friends to allocate the arenas.  This gives you the most direct access to the VM manager and makes sure that a release arena is immediately availible to the rest of the system.  It also makes sure that you don't mess with the regular heap and fragment it.
