FWIW ...

On a 64p/32G system running 2.6.31-git2-rc5, with RESOURCE_COUNTERS off,
"time make -j64" results in

real 4m54.972s
user 90m13.456s
sys 50m19.711s

On the same system, running 2.6.31-git2-rc5, with RESOURCE_COUNTERS on,
plus Balbir's "Help Resource Counters Scale Better (v3)" patch, and this
patch, results in

real 4m18.607s
user 84m58.943s
sys 50m52.682s
