[svn-r5886] Purpose:
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
