    kernel - Switch to exclusive spinlocks in kern_descrip.c
    
    * This isn't expected to have much of an effect on performance and I want
      to get rid of shared spinlocks.  If it becomes an issue for descriptor
      lookups we could actually move to a spinless lookup/hold model using
      defered frees.
