You should use the /proc instance instead.
Else, you are replacing an undocumented behavior with another.
/proc/$$/fd/1 points to the stdout
/proc/$$/fd/2 points to the stderr.
You can either just plain copy them over if CMSSW_${NJob}.stdout does not exist.
As for double file return... not clear how to get rid of it in pure Condor. Maybe you should just explicitly truncate/rename them in your script?
