REVISION SUMMARY
  The comment about 'served' refreshing all the others only applies when served is
  the head of the branchmap cache subsets. This was already no longer the case
  (and is presumably why served.hidden was added) but the comment was not
  adjusted. Currently, the "heads" of the branchmap cache subsets are the three
  specified here: visible, visible-hidden, served.hidden.

  It seems like we are not warming enought cache with the new scheme.

We are no longer warming `served` explicitly If `served` and `served.hidden` are different this will be an issue (since `served` is much more used than `served.hidden`.

I would also add a `XXX` to the comment about `visible-hidden` to encourage people to investigate. This said. The same apply, we would need to warm both `visible` and `visible.hidden` explciitly.

Oops, it seems like `visible-hidden` and `served.hidden` has inconsistent naming. Feel free to fix that along the way.
