+/*
+** A locking mechanism, built on the existing PRLock definiion,
+** is provided that will permit applications to define a Lock
+** Hierarchy (or Lock Ordering) schema. An application designed
+** using the Ordered Lock functions will terminate with a
+** diagnostic message when a lock inversion condition is
+** detected. 
+** 
+** The lock ordering detection is complile-time enabled only. in
+** optimized builds of NSPR, the Ordered Lock functions map
+** directly to PRLock functions, providing no lock order
+** detection.
+** 
+** The Ordered Lock Facility is compiled in when DEBUG is defined at
+** compile time. Ordered Lock can be forced on in optimized builds by
+** defining FORCE_NSPR_ORDERED_LOCK at compile time. Both the
+** application using Ordered Lock and NSPR must be compiled with the
+** facility enabled to achieve the desired results.
+** 
+** Application designers should use the macro interfaces to the Ordered
+** Lock facility to ensure that it is compiled out in optimized builds.
+**
+** Application designers are responsible for defining their own
+** lock hierarchy. 
+**
+** Ordered Lock is thread-safe and SMP safe.
