//
// OVERVIEW:
//
// A thread-safe container for a list of observers.
// This is similar to the observer_list (see observer_list.h), but it
// is more robust for multi-threaded situations.
//
// The following use cases are supported:
// * Observers can register for notifications from any thread.
// Callbacks to the observer will occur on the same thread where
// the observer initially called AddObserver() from.
// * Any thread may trigger a notification via Notify().
// * Observers can remove themselves from the observer list inside
// of a callback.
// * If one thread is notifying observers concurrently with an observer
// removing itself from the observer list, the notifications will
// be silently dropped.
//
// The drawback of the threadsafe observer list is that notifications
// are not as real-time as the non-threadsafe version of this class.
// Notifications will always be done via PostTask() to another thread,
// whereas with the non-thread-safe observer_list, notifications happen
// synchronously and immediately.
//
// IMPLEMENTATION NOTES
// The ObserverListThreadSafe maintains an ObserverList for each thread
// which uses the ThreadSafeObserver. When Notifying the observers,
// we simply call PostTask to each registered thread, and then each thread
// will notify its regular ObserverList.
