Yep - we are recommending to disable zeroing as soon as chunksize >512K.

Sure, but again: if writing a block larger than the underlying chunk,
zeroing can (and should) skipped. Yet I seem to remember that the new
block is zeroed in any case, even if it is going to be rewritten entirely.
Do I remember wrongly?
