Along with this ZFS import issue, it seems that hastd doesn't like it
when you fire up 24 hast devices all at once (via for loop), each with
over 100 MB of dirty data in it.  hast dumps core, kernel panics, and
system reboots.

If I do 1 hast device every 2 seconds (or however long it takes to
manually type "hastctl role primary disk-a1") then it starts up fine.

So, I can now panic my 9-CURRENT system by either:
  - starting 24 hast devices at once, or
  - importing a ZFS pool made up of those 24 hast devices, with 1
corrupted device

Isn't testing fun?  :)

I have a bunch of vmcore files from the hast crashes, not really sure
what to do with them, though.
