namecache status, slab allocator status

[Matthew Dillon]

    I'm finally making some progress on the namecache.  After a second
    attempt at trying to do all the work in a single stage failed I finally
    hit upon a methodology that will allow me to break the work up into
    three more stages.

    I am going to be making the slab allocator the default at the end
    of this week, and hopefully remove the old allocator at the end of
    next week.  There are currently two open issues regarding the
    allocator: a blocking lock obtained during a fast int which can
    lockup the system, and a reported crash during booting which has
    not yet been tracked down.
