+#   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.
+#
+# Example:
+#   When target A and target B were declared as created by a single action and
+# target A triggered running that action then, while the action was still
+# running, target B was already reporting as being built causing other targets
+# depending on target A to be built prematurely.
