* At present, the object header code maintains an image of its on disk
* representation, which is updates as necessary instead of generating on

*
* Prior to the fix that this test in designed to verify, the image of the
* on disk representation was only updated on flush -- not when the object
* header was marked clean.
*
* This worked perfectly well as long as all writes of a given object
* header were written from a single process. However, with the implementation
* of round robin metadata data writes in parallel HDF5, this is no longer
* the case -- it is possible for a given object header to be flushed from
* several different processes, with the object header simply being marked
* clean in all other processes on each flush. This resulted in NULL or
* out of data object header information being written to disk.
*
* To repair this, I modified the object header code to update its
* on disk image both on flush on when marked clean.
*
* This test is directed at verifying that the fix performs as expected.
*
* The test functions by creating a HDF5 file with several small datasets,
* and then flushing the file. This should result of at least one of
* the associated object headers being flushed by a process other than
* process 0.
*
* Then for each data set, add an attribute and flush the file again.
*
* Close the file and re-open it.
*
* Open the each of the data sets in turn. If all opens are successful,
* the test passes. Otherwise the test fails.
*
* Note that this test will probably become irrelevent shortly, when we
* land the journaling modifications on the trunk -- at which point all
* cache clients will have to construct on disk images on demand.
