-// The worker-thread will be running forever until either StopMonitoring() is
-// called from the caller-thread or the worker-thread hit some error.

-// Programming model:
-//   1. Caller-thread: Creates an object of DBusMonitor.
-//   2. Caller-thread: Calls DBusMonitor::AddFilter() one or several times.
-//   3. Caller-thread: StartMonitoring().
-//      ...
-//   4. Worker-thread: DBus signal recieved. Post a message to caller-thread.
-//   5. Caller-thread: DBusFilterBase::ProcessSignal() is invoked.
-//      ...
-//   6. Caller-thread: StopMonitoring().
-//
-// Assumption:
-//   AddFilter(), StartMonitoring(), and StopMonitoring() methods are called by
-//   a single thread. Hence, there is no need to make them thread safe.
