I believe that will still leave the per-object overrides.  We might need a ENABLE_PER_OBJECT_FASTMALLOC_NEW as well.  We should think about how to structure these defines in the context of bug 102866 as well because we'll like need to keep the global overrides but use the system malloc rather than TCMalloc.

Here are the independent choices:

1) Override global new.
2) Override per-object new.
3) When overriding global new, use the system malloc (versus TCMalloc).
4) When overriding per-object new, use the system malloc (versus TCMalloc).

Currently I believe (2) is required and (3) and (4) are coupled.  For Windows (and I believe Linux), Chromium seems to want to disable all of these options.  For Mac, Chromium seems to want (1), (2), and (4)---but not (3).
