+|Note:
+|
+| After the last rollback, the "unserved" branchheads cache became invalid, but
+| all changeset in the repo were public. So filtering wise:
+|   "mutable" == "unserved" == ΓΈ.
+|
+| As the "unserved" cache is invalid, we fall back to "mutable" cache. But not
+| update is needed between "mutable" and "unserved" cache and the "unserved"
+| cache is not updated on disk. The on disk version therefor stay invalid for
+| some time. This explains why the "unserved" branchheads cache is detect
+| invalid here.
