i've attached sched-balance-context.patch, which is the current version
of fork()/clone() balancing, against 2.6.5-rc3-mm1.

Changes:

 - only balance CLONE_VM threads

 - take ->cpus_allowed into account when balancing.

i've checked kernel recompiles and while they didnt hurt from fork()
balancing on an 8-way SMP box, i implemented the thread-only balancing
nevertheless.
