    kernel - Fix long-standing vm_map token panic
    
    * Bug turned out to be an error path in vm_map_find().
    
    * This bug ate a lot of hours from several people, but Antonio was able
      to instrument the token path in a way that allowed us to narrow down
      and locate the problem.
