Comment:

 `cabcb752d7ecc2d16e6cb630b3de0684b4f97ec5` looks good.

 As per discussion on IRC, in `c8ee12b2e8108658d647aedb92885311291b6f71`,
 it would be useful to have a comment in `consensus_cache_rescan()` about
 the meaning of `errno == ERANGE` after calling `tor_mmap_file()`.

 I think we are generally a bit inconsistent about this, but there is an
 empty line at the end of `changes/bug24099`, but it looks like that
 shouldn't really matter.

 Otherwise the patches look good.
