That's nothing to do with ZFS. Solaris 10 defines iowait to be exactly
zero. Which
it is, being essentially meaningless.

Things like vmstat and sar are a bit old anyway; I'm playing with replacements
for sar. Top is still pretty useful.

For zfs, zpool iostat has some utility, but I find fsstat to be pretty useful.
