I can't remember to have seen any mention of SWAP on ZFS being safe
now. So if nobody can provide a reference to a place which tells that
the problems with SWAP on ZFS are fixed:
 1. do not use SWAP on ZFS
 2. see 1.
 3. check if you see the same problem without SWAP on ZFS (btw. see 1.)

Bye,
Alexander.
