What build are you running?  If this is within Sun someone from the ZFS
team can go poke at it if you provide a root login (send mail to
zfs-team at sun dot com to find a candidate).  You can also try:

# mdb -k
> ::pgrep zpool | ::walk thread | ::findstack

To get an idea of where the threads are stuck.  But most likely they are
waiting on some ZIO or lock, and it would be much faster to let a ZFS
specialist take a look.
