    15 // Data Paging Stress Tests
       
    16 // Common command lines:
       
    17 // t_wdpstress lowmem
       
    18 // debug - switch on debugging information
       
    19 // silent - no output to the screen or serial port
       
    20 // single - run the tests in a single thread
       
    21 // multiple <numThreads> - run the tests in multiple threads where <numThreads> (max 50 simultaneous threads)
       
    22 // interleave - force thread interleaving
       
    23 // prio - each thread reschedules in between each function call, causes lots of context changes
       
    24 // media - perform media access during the tests, very stressful
       
    25 // lowmem - low memory tests
       
    26 // stack - perform autotest only with stack paging tests
       
    27 // chunk - perform autotest only with chunk paging tests 			
       
    28 // commit - perform autotest only with committing and decommitting paging tests 
       
    29 // ipc - perform autotest only with ipc pinning tests 			
       
    30 // all - perform autotest with all paging tests(ipc, stack, chunk and commit)
       
    31 // badserver - perform ipc pinning tests with dead server
       
    32 // iters <count> - the number of times to loop
