1. text analysis is now done before the write lock is acquired 2. there is now a pool of analysis workers 3. the size of this pool is configurable 4. this allows for documents in a batch to be analyzed concurrently as a part of benchmarking these changes i've also introduce a new null storage implementation. this should never be used, as it does not actualy build an index. it does however let us go through all the normal indexing machinery, without incuring any indexing I/O. this is very helpful in measuring improvements made to the text analsysis pipeline, which are often overshadowed by indexing times in benchmarks actually building an index.
