I have this patch on a fresh 10.0-STABLE running now for five days,
and things have improved significantly. Inactive processes are still
swapped out, but ARC no longer monopolizes all it can grab, and newly
activated processes get a chance to run quickly. Running a busy
poudriere build no longer leaves the system in unusable state
after it finishes.

I hope this gets rolled into 10.0-STABLE soon.
