+ *     The KeSwitchKernelStack routine switches from the current thread's stack
+ *     to the new specified base and limit.
+ *
+ * @param StackBase
+ *        Pointer to the new Stack Base of the thread.
+ *
+ * @param StackLimit
+ *        Pointer to the new Stack Limit of the thread.
+ *
+ * @return The previous Stack Limit of the thread.

+ * @remark This routine should typically only be used when converting from a 
+ *         non-GUI to a GUI Thread. The caller is responsible for freeing the
+ *         previous stack. The new stack values MUST be valid before calling
+ *         this routine.
