- * Monitor implementation for Native Solaris threads
- *
- * Java Monitors are implemented using one solaris mutex and two
- * condition variables. Because solaris mutex is not re-entrant we
- * cannot simply have a monitor map to a mutex as re-entering a monitor
- * would deadlock an application.
- *
- * Monitor is implemented using:
- *   mutex_t             mutex;
- *   condvar_t           cv_monitor;
- *   condvar_t           cv_waiters;
- *
- * mutex protects the monitor state.
- * cv_monitor is the condtion variable used along with mutex for
- *     supporting wait and notify on the monitor.
- * cv_waiters is used for all the threads waiting to acquire the monitor
- *     lock.
- *
- * All of the sysMonitorXXX() functions that are passed a sys_mon_t
- * assume that they get something nonnull, and only check when debugging.
