/**************************************************************************
*
* Test Description:
*
* This test will build an HDF5 file with several objects in a varying
* hierarchical layout. It will then attempt to flush the objects
* in the file one by one, individually, using the four H5*flush
* routines (D,G,T, and O). After each call to either create or flush an
* object, a series of verifications will occur on each object in the file.
*
* Each verification consists of spawning off a new process and determining
* if the object can be opened and its information retreived in said
* alternate process. It reports the results, which are compared to an
* expected value (either that the object can be found on disk, or that it
* cannot).
*
* Note that to spawn a verification, this program sends a signal (by creating
* a file on disk) to the test script controlling it, indicating how to
* run the verification.
*
* Implementation is funky, but basically, an example:
*
* Step 1. Dataset is created.
* Step 2. Verify that dataset can't be opened by separate process, as
* it should not have been flushed to disk yet.
* Step 3. Group is created.
* Step 4. Verify that group can't be opened by separate process.
* Step 5. H5Gflush is called on the group.
* Step 6. Verify that group CAN be opened, but dataset still has
* yet to hit disk, and CANNOT be opened. Success! Only the group
* was flushed.

* Test Description:
*
* This test will build an HDF5 file with several objects in a varying
* hierarchical layout. It will then flush the entire file to disk. Then,
* an attribute will be added to each object in the file.
*
* One by one, this process will flush each object to disk, individually.
* It will also be coordinating with another process, which will open
* the object before it is flushed by this process, and then refresh the
* object after it's been flushed, comparing the before and after object
* information to ensure that they are as expected. (i.e., most notably,
* that an attribute has been added, and is only visible after a
* successful call to a H5*refresh function).
*
* As with the flush case, the implemention is a bit tricky as it's
* dealing with signals going back and forth between the two processes
* to ensure the timing is correct, but basically, an example:
*
* Step 1. Dataset is created.
* Step 2. Dataset is flushed.
* Step 3. Attribute on Dataset is created.
* Step 4. Another process opens the dataset and verifies that it does
* not see an attribute (as the attribute hasn't been flushed yet).
* Step 5. This process flushes the dataset again (with Attribute attached).
* Step 6. The other process calls H5Drefresh, which should evict/reload
* the object's metadata, and thus pick up the attribute that's
* attached to it. Most other before/after object information is
* compared for sanity as well.
* Step 7. Rinse and Repeat for each object in the file.
