No Way to Set Message Queue Size on Subscriber

[GoogleCodeExporter]

I have a problem where there are a lot of compressed messages coming into my 
rosjava application, but I only care about decompressing the latest message. As 
such, I want to set the size of my subscriber queue to 1. However, there is no 
way to do this in rosjava 
as the queue size is hard-coded in 
src/main/java/org/ros/internal/transport/IncomingMessageQueue.java line 36:

private static final int MESSAGE_BUFFER_CAPACITY = 8192;

There is also, to my knowledge, no way to determine how many messages are left 
in the queue in order to decide whether to process a message or move on to the 
latest one. This, in turn, means that my node falls woefully behind in 
processing messages.

Sounds like a good idea to me.
