Create is the reintroduced construcor for the object instance. 

Create calls the inherited Create constructor to instantiate a suspended TIdUDPListenerThread. 

Create initializes the default value for AcceptWait to 1000 (ms) (1 second), and creates the the internal read buffer using the value in ABufferSize. ABufferSize is the number of bytes to allocate in the internal read buffer for datagrams received in the listener thread, and is normally set to the value in TIdUDPServer.BufferSize when the listener thread is created. 

Create also sets the server that owns the listener thread to the value in Owner. 

Use Destroy to free the object instance.
