示例1: AddEventSource
/// <summary>
/// This routine adds newEventSource to the global list of eventSources, it also assigns the
/// ID to the eventSource (which is simply the oridinal in the global list).
///
/// EventSources currently do not pro-actively remove themselves from this list. Instead
/// when eventSources's are GCed, the weak handle in this list naturally gets nulled, and
/// we will reuse the slot. Today this list never shrinks (but we do reuse entries
/// that are in the list). This seems OK since the expectation is that EventSources
/// tend to live for the lifetime of the appdomain anyway (they tend to be used in
/// global variables).
/// </summary>
/// <param name="newEventSource"></param>
