Detailed results for 2.5.62-mm3 w/plm-1592 (flock)
http://www.osdl.org/archive/cliffw/flock/mm3/index.html

I didn't have profiling turned on for this run. will be doing
a few more runs to get profile data.

The results are a very tiny bit faster than 2.5.62 stock.
(TPM change < 10% )

VMstat looks a bit different. a quick snap below.
