Version 4 fixes mem leak ID'd by Michał.

Version 3 fixed logic flaw which is supposed to prevent to sessions with
same roll being loop-back to each other, or more than one loop-back
session.

Version 2 centralizes the loop-back mechanism

Cosmetic changes reversed, as they added nothing important to the
functionality.

This allows one App using the mesh daemon to provision another.
