--------------------------------------
I think that the number 3 came from me looking at query throughput vs. size of
the .doc/.pos files for our Wikipedia dataset and figuring out the best
trade-off.

> PForUtil assumes that ForUtil.BLOCK_SIZE can be encoded in a single byte when
> generating "patch offsets". If this assumption doesn't hold, PForUtil will
> silently encode incorrect positions. While the BLOCK_SIZE isn't particularly
> configurable, it would be nice to assert this assumption early in PForUtil in
> the even that the BLOCK_SIZE changes in some future codec version.
