I did not think this would solve all the OOM problems. I do
think it will improve the situation in some instances. The cost of
suppling the additional information is small - we do not want OOM
to trigger unless we really are OOM. This patch can prevent the vm
from reporting some false OOMs...

Hope your audit discloses other problems.
