Are you looking for file names or file content? Find looks at names
then your exec'd grep will look at content in the found files. If you
want to search by file names do

  for PID in `pgrep wily`; do find /proc/$PID -name "CONTROL" -print >> trace; done

or

  for PID in `pgrep wily`; do find /proc/$PID -print|grep "CONTROL" >> trace; done
