I would definetly be willing to commit something as long as I can
verify it on a few systems first.

|committers would be willing to commit this patch.
Perhaps worth mentioning that I already have a patch and the 20-25% savings
is real savings, not estimated from prof numbers. However the patch needs
refined to be ready for a commit.
