+// f32test\demandpaging\t_pagestress.cpp
+// Demand Paging Stress Tests
+// t_pagestress.exe basically attempts to cause large ammounts of paging by calling
+// functions (256) which are alligned on a page boundary from multiple threads.
+// There are mulitple versions of t_pagestress installed on a test system to test rom
+// and code paging from various media types.
+// Usage:
+// t_pagestress and t_pagestress_rom
+// Common command lines:
+// t_pagestress lowmem
+// debug - switch on debugging information
+// silent - no output to the screen or serial port
+// check - check the allignments
+// single - run the tests in a single thread
+// multiple <numThreads> - run the tests in multiple threads where <numThreads>
+// 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
+// forward - patern in which to execute function calls
+// backward - patern in which to execute function calls
+// random - patern in which to execute function calls
+// all - patern in which to execute function calls (forward, backward and random)
+// inst - for debugging a parameter passed to a spawned exe to give it an id.
+// iters <count> - the number of times to loop (a '-' means run forever)
+// t_pagestress causes a large ammount of paging by repeatedly calling
+// 256 functions which have been aligned on page boundaries from
+// multiple threads.
+// 1 - a single thread calling all functions
+// 2 - Multiple threads calling all functions
+// 3 - Multiple threads calling all functions with a priority change
+// after each function call
+// 4 - Multiple threads calling all functions with background
+// media activity
+// 5 - Multiple threads calling all functions with media activity and
+// a priority change after each function call
+// 6 - Multiple threads calling all functions with process interleave
+// 7 - Multiple threads calling all functions with process interleave
+// and a priority change after each function call
+// 8 - Multiple threads calling all functions with process interleave
+// media acess and a priority change after each function call
+// 9 - Multiple threads calling all functions with low available memory
+// 10 - Multiple threads calling all functions with low available memory,
+// starting with initial free ram.
