   8 #   Added to guard against a bug causing targets to be used before they
   9 # themselves have finished building. This used to happen for targets built by a
  10 # multi-file action that got triggered by another target, except when the
  11 # target triggering the action was the first one in the list of targets
  12 # produced by that action.
  13 #
  14 # Example:
  15 #   When target A and target B were declared as created by a single action with
  16 # A being the first one listed, and target B triggered running that action
  17 # then, while the action was still running, target A was already reporting as
  18 # being built causing other targets depending on target A to be built
  19 # prematurely.
