If I've understood it right from the mailing lists, ZFS returns memory=20
back to the OS from caches somewhat lazily, so in times of high memory=20
load ZFS system can cause some swapping.

Of course, once the situation with memory load is over, swap will=20
still continue to show the max amount swapped ever, even if everything=20
is again back in real memory.

So nothing to worry about I'd say.
