UMA questions

I have a couple of questions regarding UMA things which are not explained in
the relevant man pages (and UTSL is a little bit tough):
1. UMA zones do not show up in the output of 'vmstat -m'. Is there a way
to get information on how much memory each UMA zone is using?
Example: "sackhole", "tcptw", ...
2. What does the flag UMA_ZONE_ZINIT do exactly?
3. What does the flag UMA_ZONE_NOFREE prevent exactly? Will it prevent any
zone/slab of this type to be free'd ever again? This way the zone can
only grow and not shrink after transient peaks?
