That could be something from the LX code, but I'm not seeing it in my 020 zones (and I've several of them).

I've probably missed out on those mails, but who else has seen this issue (precisely zones taking forever to shutdown)?  I know about the message, but I don't see zones being jammed up on shutdown.

I wonder if it's "init 6" specifically?  I use reboot(1M) command, so it does not go through the inittab(4) sequence.  Now I'm more fascinated to know what process(es) are hanging, because I suspect they arrive via "init 6".
