+// Overview:
+// Test for race conditions in emulator scheduler
+// API Information:
+// RMessage2, RMessagePtr2, RSessionBase, CSession2, CServer2, CPeriodic
+// Details:
+// - The client and server shuttle messages back and forth with variable timing
+// - The client also has a periodic timer, which fires at a random phase relative to the IPC
+// - The client should have higher priority than the server
+// - The race may occur when the timer interrupt preempts kernel code and disables interrupts
+// - The "preempted" code nonetheless runs and sees the "impossible" disabled interrupts
+// - The result is a precondition failure at a random point
+// Platforms/Drives/Compatibility:
+// Will run on all platforms, but precondition failure is expected only on the UDEB emulator.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
