It seems like this should be a "large" speedup.

(I think) our test time is dominated by allocator time because we have the same fixed size and number of blocks for tests as for our wikipedia ingestion build.

This is the half of #275 that wasn't just a display issue in `TermTableBuilder`. If we re-run the `bitfunnel termtable` on `chunked1` from http://bitfunnel.org/wikipedia-as-test-corpus-for-bitfunnel/, we get varying results from `bitfunnel...

See #314 for description and discussion, including why this bug was introduced.

1. Dedup buffer has to get wider. For example, it would have to go from `2**6` to `2**13`. This seems ok because we only clear the entirety when we start...

This is likely a `Workbench` issue, but until that's confirmed I'm going to leave this here. We have terms like `0,1,2,3,4,5,6,7,8,9`, `1,2,4,8,16`, `1,2,3,4,5`, etc. It's possible that this is "correct"...

This is running 16 threads on a quad-core 8 HT machine. Looks like roughly 30% of query time is token-related here. I'm not familiar with the Instruments profiler so I...
