Yes, it should.  You're running a more modern (future) Solaris release
than I've got here (10U3).

Yikes.  I didn't even want to think about that.  For ZFS, I'd think it
shouldn't matter, though.  Either "the" ueber-block gets written, or it
doesn't.  One then only depends on the whole cache getting flushed to disk
eventually, right?
