Description:

Caches blocks of messages; instead of sending multiple blocks containing messages, the messages are grouped. When calling wait_message_ID alias WaitMessage or getting a property, the buffer will be flushed. The number of calls to BeginUpdateSession must match the number of calls of EndUpdateSession; when this happens, the data will be flushed over the network, and all the messages will be send in one virtual packet (conserving both speed, and bandwidth).
