Using a "flag file" instead of a config setting gives more flexibility;
like no need to restart in order to turn this feature on/off, or can select to
catch errors only in few nodes, and last -- can free the looping thread by
deleting this "flag file".
I also plan on posting an announcement on the dev list about this new
"feature", and see if there's any feedback.
