No idea. You may just make separate partition for swapping and it will 
work. Good if you have swap "just for sure".

If your system needs swapping under normal operation, using ZFS is really 
bad idea as it needs lots of memory - which you are already short of.

With RAM costs of <20$/GB (DDR2) it's best to get as much memory as your 
software needs.
