  * Overhaul all the caching
  Ignore-this: e82f108830a5b42576bd4b0bba677ed4
  Separate the previous uses of caches into two kinds: 1. simple
  in-memory vars and 2. proper caches. For the former we just add a
  simple strict wrapper around MVar, with read/write/modify operations,
  while for latter kind we use asynchronous caches that are constructed
  with their update action.
  
  Then update the features to use the appropriate kind of cache.
  Additionally, the old async cache infrastructure had a feature to
  disable updating of caches for the benefit of bulk import operations.
  The corresponding thing in the new infrastructure is a tunable knob
  to delay cache updates so that more changes can accumulate before doing
  the expensive cache update operation.

  * Move a use of runHook into the feature that owns the hook
  Ignore-this: ffaef756e8b9c49027a4cf867c64d0be
  Other features should not really prod hooks.
