i'm certainly not claiming this is a general solution for all possible arms, but for kw-style caches (16-byte lines) and kw-style hardware (very little cache-coherency), i think the idea has a lot of merit. especially with quickfit with external (that is cache-coherent) tracking. i really do like your cc malloc, though. very clean. though i had to look twice to verify i understood the pointer orthodontics. ☺. - erik
