    sys/kern             kern_exit.c sys_process.c sysv_shm.c 
                         vfs_aio.c 
    sys/vm               vm_glue.c vm_map.c 
  Log:
   - Use atomic ops for updating the vmspace's refcnt and exitingcnt.
   - Push down Giant into shmexit().  (Giant is acquired only if the vmspace
     contains shm segments.)
   - Eliminate the acquisition of Giant from proc_rwmem().
   - Reduce the scope of Giant in exit1(), uncovering the destruction of the
     address space.
