On the flip-side, any swap that you do define on your SSD is unlikely to

Solaris will reduce the size of the zfs ARC before it starts filling swap.
Well, for one, I've had non-rpool swaps for ages, and it is not a
problem. Swap is imported during svc:/filesystem methods by parsing
/etc/vfstab, and the worst that can happen (i.e. with an absent
data pool) is that a swap device won't mount. At least back then
this was not a fatal error that would break system boot.
It might be argued whether the area for swap might better be used
as L2ARC, or conversely if this would put excessive wear onto rpool
and decrease its reliability...
