* Accepted concensus on opensource benchmarks to use for validating
allocator changes.
* Stable API that allows interaction with allocator running in an application.
- Usable by a debugger, audit library etc.
* Application hook to control arena creation.
- Can use allocator API and application specific information to make
decisions.
* Systemtap probes
- What do we measure? What additional probes do we need?
That's just off the top of my head... hope it helps.
Cheers,
Carlos.
