By the way, the above tests where done on evolution.

Secondary measurements in single user mode show the following. On a
sleeping funit-child with 12 threads:

fstack: up from 1.5915 to 1.596
fcore: up from 1.039 to 1.265

which is even weirder, but the numbers show that in general new is
better than old:

Old fstack: 1.616, 1.626, 1.456* 1.616, 1.621, 1.614
New fstack: 1.593, 1.593, 1.593, 1.601, 1.598, 1.600

Except for the old fstack getting a burst of speed in the middle there,
the new method is consistently faster.

Old fcore: 0.479, 1.423*, 0.451, 0.933*, 0.968*, 1.977*
New fcore: 0.429, 0.429, 3.106*, 0.433, 2.754*, 0.437

Here again we have weird hangs at odd times. I don't know why.
