this text suggests WHAT to do, but not WHY to do it.  In my opinion any
suggested workflow shall be accomplished by problem description, so
that the implementers can understand the  rationale of the proposed
solution (and thus higher the chances, that the endless loops are
prevented).  I put the problem description in my previous mail on this
mailing list.

Greetings
