And yes, this has nothing to do with zones :-).
That leaves unanswered the underlying question: why do you need to do
this at all? Isn't the ZFS ARC supposed to release memory when the
system is under pressure? Is that mechanism not working well in some
cases ... ?
My understanding is that if kmem gets heavily fragmaneted ZFS won't be
able to give back much memory.
