This is good for ... what ...? Instead of "this is good for ... what ...", let me know what you think of: This allows for greater bitmap coverage (and, thus, performance when using bitmaps) of repositories with many references which ordinarily would not receive full coverage. > Expecting a reroll. I'm planning on sending one soon, but was hoping that Peff or someone else familiar with the bitmap machinery would look over some of the technical details first. > cf. > source: Thanks, Taylor
