But if it is just temporary during intersection, you wouldn't want every object to have it's own allocation.

Two other ideas come to mind:
- Make per-thread new/delete/malloc/free. Might be a bit of work, and still might be too slow for intersect.
- Make a method in RenderContext similar to getScatchpad that returned a pointer to a buffer and would reallocate that buffer if it were too small. Abe, is this what you had in mind?

Who needs to access the memory. Per thread memory is often stored at the accessor's level. See JitterSampler for an example.

Hey,
I need some per-thread memory during intersection.
I think I can hack this into the code (some singleton sitting out there with buffers that are indexed by RenderContext::proc).
Does anyone have an idea of how to more gracefully add it? Maybe mutable as part of the render context?
