  32  * DESCRIPTION
  33  *     Single thread loads a short chain of fat classes
  34  *     with a long chain of loaders (NxM load attempts).
  35  *     Then, memory stress is induced to unload the classes.
  36  *     The test is deemed failed if loading attempt fails;
  37  *     or if the tested VM crashes.
  38  *     The test repeats until the given number of iterations,
  39  *     or until a timeout.
