Peter, I'll try to minimize the delta between the patch set revisions
so that this could be pulled in the near future (maybe having odds
to make into 3.19) and do only fixes to those issues that are blockers.

Would you mind if I fixed dev logging stuff after the patch set has
been pulled? 

Writing this down anyway to my backlog.
