Looks like Mark is currently working on this: https://bugs.webkit.org/show_bug.cgi?id=69390.

Once that patch is in the tree, perhaps you can transform the code that iterates objects in the heap to iterate based on this per-object size information, instead of constant size classes.

Another interesting task is to profile different workloads using the timing code Oliver just checked in, and identify performance issues in the GC implementation.
