A mistake was made in generating some of the S4 workunits

A mistake was made in generating some of the S4 workunits. All workunits whose names start with 'h1_' (LOWER CASE!) have been cancelled (though user/hosts/teams will still get credit for any work done). To avoid wasting CPU time, any running 'h1_' (LOWER CASE ONLY!) work can be aborted 'by hand' if desired. Some detail is in this message board thread.
