The Completely Fair Scheduler was merged for the 2.6.23 kernel. One CFS feature which did not get in, though, was the group scheduling facility. Group scheduling makes the CFS fairness algorithm operate in a hierarchical fashion: processes are divided into groups, and, within each group, processes are scheduled fairly against one another. At the higher level, each group as a whole is given a fair share of the processor. The grouping of processes is done in user space in a highly flexible manner; the control groups (formerly 'process containers') mechanism allows a management daemon to classify processes according to almost any policy.

no, the case i am remembering was clearly a bug in the database software, which actually was fixed in a later release.
so YOU should clear YOUR mind..
and btw, CFS may not provide as high throughput, but that comes at the price of increase interactivity. and while CFS is not as good as it could be(as it havent gotten as good as SD), its still alot better interactivity wise than what we had before.
