+// Overview:
+// Test nanokernel implicit system lock
+// API Information:
+// NKern::LockSystem and NKern::UnlockSystem
+// Details:
+// - Load and open the logical device driver ("D_IMPLICIT"). Verify results.
+// - The LDD uses three separate threads to test the nanokernel implicit 
+// system lock with changing priorities, round-robin and a "dry run".
+// - Close the channels and verify results are as expected.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
