+/*
+The whole thing is a thread that runs in a loop, waiting for either:
+ "finished chunks" (ChunkReady()), or
+ "chunks to send" (QueueSendChunkTo() )
+to come to a queue.
+And once they do, it requests the chunk data and sends it all away, either
+ broadcasting (ChunkReady), or
+ sends to a specific client (QueueSendChunkTo)
+Chunk data is queried using the cChunkDataCallback interface.
+It is cached inside the ChunkSender object during the query and then processed after the query ends.
+Note that the data needs to be compressed only *after* the query finishes,
+because the query callbacks run with ChunkMap's CS locked.
