Yes. I saw the attached patches. I am definitely going to apply them and see how they work out.

In his last patch, there are a bunch of magic numbers used to reserve free page blocks
at different orders. I think that is the most interesting part. If Thomas can share how
to determine these numbers with his theory based on workloads, hardware/chipset, that would
be a great guideline for sysadmins to take advantage of the patches.
