Given that this information is repeated on all revisions, and that
those files will travel back and forth, perhaps another change that
could be made is "compressing" those strings:

  <rev committer="..." inv_id="..." ...>
  <msg>...</msg>
  <parents>
    <rev_ref id="..." />
    <rev_ref id="..." />
  </parents>
  </rev>

or even

  Committer: ...
  Inventory: ...
  Message:
    ...
  Parents:
    ...
    ...

in rfc822 style, which is weave-friendly.
