+ *   work queue.
+ *
+ *   This is a user mode work queue.  It must be used by applications for
+ *   miscellaneous operations.  The user work thread must be started by
+ *   application start-up logic by calling work_usrstart().
+ *
+ * Input parameters:
+ *   argc, argv (not used)
+ *
+ * Returned Value:
+ *   Does not return
