- the case of 'fan-like' processor was previously assumed to be rare (see merge-request !490 and issue #2084). However, Vaggelis Papoutsis noticed that even fairly normal geometries can trigger problems. - replaced the old patch/patch matching style with a more general edge-based synchronisation and matching that appears to handle the corner cases inherently. The internal communication overhead is essentially unchanged, and the logic is simpler. ENH: additional framework for managing patch connectivity
