+// Description:
+// e32test\bench\t_kernbm.cpp
+// Overview:
+// Benchmark the performance of some kernel functions including RTimer
+// and RThread. Calculation time required for creation & closing of
+// timer objects, suspension of threads, handling kernel messages, and 
+// the number of threads created and stopped within a fixed time period.
+// API Information:
+// RTimer, RThread.
+// Details:
+// - Calculate and display the time required to create and close 1000 
+// thread-relative timer objects.
+// - Count and print the time taken to suspend the thread for 100000 times.
+// - Count and display the time consumed for 100000 kernel messages.
+// - Get and print the number of threads created and stopped within a 
+// specified timeframe, verify the ExitType, and ExitReason of the threads.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
