Comment(by richard):

 Also, I wonder if it's just the doclength lists which could do with
 improved skip_to() ability - it's possible the other posting lists could
 also benefit, but aren't causing quite such obvious problems: either
 because they're being skipped through less often, or because the chunks
 contain fewer items since each item is larger - with flint, the items
 contain the doclengths, so they're going to be quite a bit larger.
