I was considering both. Use a timer set for X milliseconds (could be user 
definable in order to account for different different systems) and also have 
an explicit flush command for high level plotting functions that want it. The 
last thing we want to do is to have everything being sent one by one to the 
visualisation app.

I wouldn't expect the timer would need to autoflush after more than about 
2-20ms bearing in mind that it would be within a dynamic Octave plugin so 
there would not be any latency to deal with.
