---------------------------------------

GitHub user cwestin opened a pull request:

    https://github.com/apache/drill/pull/194

    DRILL-1942-vector-test

    Additional tests added to TestValueVectors for serialization and loading; these tests were used to find and debug issues with DrillBuf slicing. Some light cleanup of a few vector implementations.
    
    Unit tests pass.
    Regression suite has a few (known recurring) failures:
    - timeouts while waiting to send intermediate work fragments
    - timeouts for "Fetch parquet metadata" tasks not complete
    - Selected column 'dir0' must have name 'columns' or must be plain '*'

> We're using a lot more memory than we think we should. We may be leaking it, or not releasing it as soon as we could. 
> This is a call to come up with some improved tracking so that we can get statistics out about exactly where we're using it, and whether or not we can release it earlier.
