--- Comment #1 from Alexander Motin <mav@FreeBSD.org> ---
Yea, queuing multiple tasks for arc_prune same time makes no sense and in
addition to CPU usage you see likely causes over-pruning after the pressure is
already resolved.  After thinking of several possible approaches I am going to
unify FreeBSD code with Linux there, that should be good step by itself.
