        // returned correctly and there is no seg fault.

//  Modifications:
//    Jeremy Meredith, Thu Nov  2 14:10:51 PST 2000
//    Added another sanity check.
//
//    Hank Childs, Wed Jan 17 11:05:20 PST 2001
//    Added plots.
//
//    Jeremy Meredith, Thu Mar  1 13:41:13 PST 2001
//    Disable the section of code which allows re-using of entire networks.
//    This allows us to continue caching networks, but avoids the temporary
//    problem where different networks' plots might use different values
//    but we have not checked to see if the plots are equivalent.
//    Also....  I changed the way the networks are hooked up to allow for
//    zero-length pipelines.
//
//    Hank Childs, Wed Mar  7 11:33:51 PST 2001
//    Timestep now an argument to the database instead of set as a global.
//
//    Kathleen Bonnell, Tue May  1 16:57:02 PDT 2001 
//    Added try-catch block so that exceptions could be rethrown. 
//
//    Hank Childs, Tue Jun 12 14:55:38 PDT 2001
//    Incorporate data specifications.
//
//    Jeremy Meredith, Tue Jul  3 15:18:55 PDT 2001
//    Modified to better handle interruption of pipeline execution.
//
//    Brad Whitlock, Mon Oct 22 18:33:37 PST 2001
//    Changed the exception keywords to macros.
//
//    Jeremy Meredith, Fri Nov  9 10:29:17 PST 2001
//    Moved code to finish network matching into EndNetwork.
//    Added sending of window attributes into plot->Execute.
//
//    Kathleen Bonnell, Tue Nov 20 12:35:54 PST 2001
//    Set flag in dataSpec based on value of requireOriginalCells. 
//
//    Hank Childs, Tue Jun 18 16:49:01 PDT 2002
//    Set MayRequireZones before Executing.
//
//    Mark C. Miller, 10Nov02
//    Made changes to support scalable rendering
//
//    Brad Whitlock, Thu Jan 16 11:07:10 PDT 2003
//    I replaced the return in the TRY/CATCH block with CATCH_RETURN2 so that
//    fake exceptions work again.
