[svn-r5814] Purpose:

    Bug Fix

Description:
    It was possible to create corrupted metadata information (either in memory
    or in the file or both) with a parallel I/O program because of the way
    metadata writes were being handled for writes out of the metadata cache.

Solution:
    Added a dataset transfer property called "block before metadata write"
    which is used by the MPI-I/O and MPI-posix drivers to sync up all the
    processes before attempting a metadata write.  This property is currently
    only for metadata writes from the metadata cache.

Platforms tested:
    IRIX64 6.5 (modi4) w/parallel
