  * DESCRIPTION: Release all mutexes held by this thread
  *
+ * NOTE: This function is called as the thread is exiting the interpreter.
+ * Mutexes are not released when an individual control method is exited, but
+ * only when the parent thread actually exits the interpreter. This allows one
+ * method to acquire a mutex, and a different method to release it, as long as
+ * this is performed underneath a single parent control method.
