You know, thinking about this some more ... I previously wrote a 
netio-based "dense" storage form for rosters, which used less space and 
was less compressible (the normal form is highly redundant). I discarded 
it because it didn't turn out to be much faster; but maybe I should 
revive it. If most other fulltexts are small enough, maybe the 
performance win is big enough to make the space cost worthwhile, and we 
can drop gzip entirely. Or we can gzip only non-roster fulltexts. Either 
way, might remove some time spent in gzip.
