Comment (by kevan):

 So it turns out that the files are already implemented in a way that
 allows power-of-two updates like I described above.
 attachment:393status27.dpatch fixes the update behavior to take advantage
 of this, includes some new tests, and fixes some bugs revealed by those
 new tests. The mutable filenode code can now do O(update size) updates to
 MDMF mutable files in general.
