Generally that is true for vm_map_lock() because it is a sx_lock (thus sleeping) but in this case it is used a trylock operation that won't sleep (and I assume that is why it is used), thus it is not a problem. The vmspace refcounting doesn't impose any extra-constraint instead, thus the lock dance is not required here I think. Thanks, Attilio -- Peace can only be achieved by understanding - A.
