To be honest, I think by now we've found so many problems around short backing files, each with a non-trivial fix, that I don't think we can have a reasonably complete fix in -rc3 without risking breaking everything. None of the problems are new, in fact I think they have existed since day one of resize/commit, and nobody has reported problems before, so they can't be hitting a large number of users. So, reluctantly, I have to admit that both series and whatever we'll add on top are probably better kept for 5.0 (and 4.2.1) rather than added very late into 4.2. Kevin
