  71 Excerpts from Mark Anderson's message of Wed Feb 17 14:23:48 -0500 2010:\r
  72 > But if we have notmuch as a cache of the tags, then don't we already\r
  73 > know the tree objects that need updating?  Yes, we would probably need\r
  74 > some consistency checks for when things don't work as planned, but in\r
  75 > the common case we ought to always know.\r
  76 > \r
  77 Cached or not, rewriting would still be an incredibly (e.g.\r
  78 prohibitively or close to it) expensive operation for a large mailstore.\r
  79 \r
  80 > Perhaps I'm misunderstanding these tree objects, and you're suggesting\r
  81 > that we don't even tell notmuch about them.\r
  82 > \r
  83 I think it would be unwise to teach notmuch anything about the\r
  84 underlying store. That would be leaking way too many implementation\r
  85 details into \r
