## Detailed Description

Utility class for exception-safe mutex locking.

Usage example:

       {
         Glib::Mutex::Lock lock (mutex); // calls mutex.lock()
         do_something();
       } // the destructor calls mutex.unlock()

  As you can see, the compiler takes care of the unlocking. This is not only exception safe but also much less error-prone. You could even `return` while still holding the lock and it will be released properly.

Examples:

  thread/thread.cc.
