-    Set an upper limit on the execution time of an ExpressionTool.
-    A ExpressionTool whose execution duration exceeds the time
-    limit may be preemptively terminated and considered failed.
-    May also be used by batch systems to make scheduling decisions.
-    The execution duration excludes external operations, such as
-    staging of files etc, and only counts wall-time for the
-    evaluation of the expression itself.
