commit 4e23f366eb82dff7126b9988c5f77d13540d04e5

    kernel - Fix mbuf header exhaustion w/ degenerate unix domain socket case
    
    * Increase the number of mbuf headers to accomodate a degenerate
      fd-passing case with chains of unix domain sockets, one fd per
      socket.
    
    * This does not address other mbuf exhaustion issues which can crop
      up in a user ddos attack due to the default number of fds a user
      is allowed to own.
