+Values aside from EXIT_SUCCESS and EXIT_FAILURE can be used to indicate
+finer gradations of failure.  If this is the only information available
+to the caller, clamping such values to EXIT_FAILURE loses information.
+If there are other ways to indicate the problem to the caller (such as
+a message to stderr) it may be ok to clamp.  In all cases, it is the
+relationship between the program and its caller that must be examined.
