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