0001 # This is intended to test whether fast cloning is
0002 # actually occurring when it should. It uses a trick
0003 # to check.  With this configuration, fast cloning should
0004 # occur.  An exception unrelated to fast cloning is forced
0005 # on the second event, and after that there should be a
0006 # secondary exception as the Framework attempts to write out
0007 # and close the root files.  This secondary exception occurs
0008 # because the Event TTree should be imbalanced.  This imbalance
0009 # is caused by fast cloning.  The TTree would not be imbalanced
0010 # if fast cloning was not occurring.  The shell script that
0011 # invokes cmsRun with this configuration then uses grep to
0012 # look for the expected inbalance error and this verifies
0013 # that fast cloning was occurring.
