HAMMER is progressing well.  The filesystem basically works, but there
    are some major pieces missing such as, oh, the recovery code, and I
    still have a ton of issues to work through... the poor fs blows up
    when it runs out of space, for example, due to the horrible spike 
    implementation I have right now.

    It isn't stable yet but some major milestones have been achieved.  I am
    able to cpdup, rm -rf, and perform historical queries on deleted data.

    Here is a quick example:
    
# newfs_hammer -L TEST -S /var/vkernel/hammerimg.01 /var/vkernel/hammerimg.02
... start up vkernel ...
# mount_hammer /dev/vkd2 /dev/vkd3 /mnt
# cpdup / /mnt/copy
# sync
# hammer now
0x47799042
# rm -rf /mnt/copy
...
# cd /mnt/copy@@0x47799042
[access originally cpdup'd data, even though you deleted it all]

    Please note that HAMMER is *NOT* yet ready for wider testing.  Please
    don't start reporting bugs yet, because there are still tons of things
    for me to work through.
