Comment (by wfn):

 TL;DR of my thoughts right now:

  * I don't think any zlib-compressed-data caching happens (can't find any
 in `buffers` or `torgzip`, etc.)
  * Nevertheless, the diffs ''should really be'' just because directories'
 view of relays and their descriptors is always changing (it would be nice
 to confirm this in a definite manner, of course.) Also, some caching could
 be happening "somewhere else" (i.e.: I don't know.)
  * `all.z` is a zlib stream, and as far as zlib streams go, everything is
 OK with it.
  * I'm not really qualified to make the above statements, sorry. i.e.:
 someone else should take a look at this, too.
