This is a great bug to fix.
I think the remaining question we should investigate is whether
sync(2) should do anything at all in a non-global zone (or should
somehow be restricted in scope). Probably we should check in with the
VM and/or UFS folks about this.
I know that at some point the performance guys wanted to make sync's by
non-root users do nothing, but IIRC it was deemed too risky or something.
