But whether my analysis is accurately pin-pointing the problem or not, with all respect, I think I'll trust Val's word over yours that there *is* a problem :-).

Val is definantly right about the difficulty in doing it the best possible way, as I noted my approach would run some possibility of the COW causing out of memory problems, but I suspect that it's a 90% solution.

I guess this is complicated by the question of when dirty blocks get flushed, and in how large batches; maybe it's solvable. But I don't think memory is the main concern, at least.
