  # Creating biblio instance for testing.
  # Creating item instance for testing.
  # Deleting item testing instance.
  # Deleting biblio testing instance.
  # Deleting borrower.
  t/db_dependent/Reserves.t .. ok
  All tests successful.
  Files=1, Tests=4,  1 wallclock secs ( 0.02 usr  0.01 sys +  0.39 cusr  0.02 csys =  0.44 CPU)
