aim7, using the compute workfile, and a datapoints file containing
$Tasks. multitask -nl -f will prompt for the datapoints file. You'll
have to bump /proc/sys/kernel/sem if it's left at default by your
distro. If you want, I can send you a tarball offline.

I don't _think_ you'll fix the sweet spot without setting knobs such
that last_buddy can do its thing, but go for it ;-)
