THis may also have to wait for a future version of ZFS. I remember
reading about this kind of thing as an upcoming feature in Solaris. I
believe the way this feature would work is that ZFS would allow creating
the ZIL on a different pool to the filesystem - i.e. create a zpool on
the CF card and get the ZIL to live there.
