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