It seems your original question hasn't been answered yet... :-)

I have used U4 with the complete /var on zfs for quite a while and
have not encountered any problems.  My usual setup for mirrored root
disks is:

  what   where                  how

  /      /dev/md/dsk/d0         ufs
  swap   /dev/md/dsk/d1         swap
  ROOT   cXt0d0s3 + cXt1d0s3    zpool

The ROOT pool contains /var, /opt, and /export.  I set both quota
and reservation for /var to be on the safe side.

I have not done any stress testing with zones, but normal use
is absolutely trouble-free.
