   @regner loading the db info for every db at once is prohibitively expensive on disk and RAM, especially on busy clusters where doing so screws up both disk caching and our LRU cache.
   
   Our couch fs crawler is deterministic, and it's good we don't have to load it all into memory at once. Since we need to keep that mechanism, saving our current work point when the autocompactor is paused, then resuming from that point is a simple way to solve the problem at hand without destroying performance.
