Bug fix

Description:
    Correctly apply filters (like compression) to fill values in chunks that
    are pre-allocated.

    This is OK in parallel also, since all the chunks are identical at this
    point and any chunk may be written by any process.

Platforms tested:
    FreeBSD 4.6 (sleipnir) w/parallel
