Bug Description
This may affect knits as well as packs. It's driven by the graph.heads()
call being bad-O today.
On knits we can choose to do more IO - read the per-file graph to decide
even when commonly we don't actually need to - to trade off the heads
cost.
On packs the index access is cheaper (partial reads are supported) so we
have a patch here that makes it faster.
