Details

To work out whether to pretenure object groups in the future we uses a 16 element table keyed on a hash of the ObjectGroup pointer. If there are collisions then the first group with that hash takes precedence. It's possible this is causing us to miss groups that should be tenured.

We've removed pretenuring based on ObjectGroups.
