question: private static void pushTransactionStartStamp ( Transaction t ) { Map < Transaction , Timestamp > map = suspendedTxStartStamps . get ( ) ; Timestamp stamp = transactionStartStamp . get ( ) ; if ( stamp != null ) { map . put ( t , stamp ) ; } else { Debug . logError ( "Error in transaction handling - no start stamp to push." , module ) ; } }
target:  Put the stamp to remember later
