   This should not be done.

   You dont really need to upgrade daily, you are just overloading
   freebsd cvsup servers.

   Also, why to make all the source tree if you just get few
   modifications per day? It would be wise to know what part or the tree
   was updated and just compile it or let the whole compilation for
   later.

   If you want to see your machine working at 100% cpu, learn prolog.
