Yeah, but overall the performance of his recent patch is pretty amazing.

It's really good that Linux is finally getting a VM that behaves well and
can keep the working set in memory without heavy IO activity flushing out
critical process pages. The performance of Riel's VM system should hold for
server activity too. And adding something like thrash control to help make
sure aging still works (without statistical scattering) under heavy load
should allow Riel's VM to progress under loads that would freeze previous VMs.
