-/**
- * @class ACE_Thread_Mutex
- *
- * @brief ACE_Thread_Mutex wrapper (only valid for threads in the same
- * process).
- *
- * This implementation is optimized for locking threads that are
- * in the same process. It maps to <CRITICAL_SECTION>s on NT
- * and <ACE_mutex_t> with <type> set to <USYNC_THREAD> on UNIX.
- * ACE_Thread_Mutex is recursive on some platforms (like
- * Win32). However, on most platforms (like Solaris) it is not
- * recursive. To be totally safe and portable, developers
- * should use ACE_Recursive_Thread_Mutex when they need a
- * recursive mutex.
