Yeah, this was my fault :(

I've had a chance to test this now, and everything feels great. I did
some benchmarks for 2.6.23-rc1, 2.6.23-rc6-cfs, and
2.6.23-rc6-cfs-devel:
lat_ctx -s 0 2:
2.6.23-rc1	2.6.23-rc6-cfs	2.6.23-rc6-cfs-devel
   5.15		   4.91			5.05
   5.23		   5.18			4.85
   5.19		   4.89			5.17
   5.36		   5.23			4.86
   5.35		   5.00			5.13
   5.34		   5.05			5.12
   5.26		   4.99			5.06
   5.11		   5.04 		4.96
   5.29		   5.19		  	5.18
   5.40		   4.93		   	5.07

hackbench 50:
     2.6.23-rc1	2.6.23-rc6-cfs	2.6.23-rc6-cfs-devel
	6.301 		5.963 		5.837
	6.417		5.961 		5.814
	6.468 		5.965 		5.757
	6.525 		5.926 		5.840
	6.320 		5.929 		5.751
	6.457 		5.909		5.825

pipe-test (http://redhat.com/~mingo/cfs-scheduler/tools/pipe-test.c):
     2.6.23-rc1	 2.6.23-rc6-cfs	2.6.23-rc6-cfs-devel
	14.29		14.03		13.89
	14.31		14.01		14.10
	14.27		13.99		14.15
	14.31		14.02		14.16
	14.53		14.02		14.14
	14.53		14.27		14.16
	14.51		14.36		14.12
	14.48		14.33		14.16
	14.52		14.36		14.17
	14.47		14.36		14.15

I turned the results into graphs as well. I'll attach them, but they're also at:

http://www.healthcarelinen.com/misc/pipe-test_benchmark.png

The hackbench and pipe-test numbers are very encouraging. The avg
between the 2.6.23-rc6-cfs and 2.6.23-rc6-cfs-devel lat_ctx numbers
are nearly identical (5.041 and 5.045 respectively).
