   305 ### What should be done with a cached delta and its base ?

   306 

   307 # Ignore the cache when considering candidates.

   308 #

   309 # The cached delta might be used, but the delta base will not be scheduled for

   310 # usage earlier than in "normal" order.

   313 # Prioritize trying the cached delta base

   314 #

   315 # The delta base will be tested for validy first. So that the cached deltas get

   316 # used when possible.
