stressapptest is a userspace test, primarily composed of threads doing memory copies
and directIO disk read/write. It allocates a large block of memory (typically 85% of
the total memory on the machine), and each thread will choose randomized blocks of
memory to copy, or to write to disk. Typically there are two threads per processor,
and two threads for each disk. Result checking is done as the test proceeds by
CRCing the data as it is copied.
