+// Overview:
+// Test the platform security aspects of the RThread class
+// API Information:
+// RThread
+// Details:
+// - Test renaming the current thread and renaming a thread from 
+// another thread. Verify results are as expected.
+// - Test resuming a thread from a different process and from the
+// process that created the thread. Verify results are as expected.
+// - Verify that other processes can not suspend a thread and that the
+// creating process can.
+// - Perform a variety of tests on killing, terminating and panicking
+// a thread. Verify results are as expected.
+// - Test setting thread priority in a variety of ways, verify results
+// are as expected. Includes ensuring real-time priorities are
+// unavailable to processes without capability ProtServ.
+// - Test RequestComplete and RequestSignal on a thread in a variety 
+// of ways, verify results are as expected.
+// - Test SetProcessPriority on a thread in a variety of ways, verify 
+// results are as expected.
+// - Test the Heap, ExceptionHandler, SetExceptionHandler, 
+// ModifyExceptionMask, RaiseException, IsExceptionHandled, 
+// SetProtected and SetSystem methods. Verify results as expected.
+// Platforms/Drives/Compatibility:
+// All.
