Ok, here is the code as a whole. I think it's still short enough to ilustrate the problem. Just start it with the datafile "elips" as an argument

The time seems to grow with number of cycles rendered even when no more points are added (the points are calculated with a continous rate in a background thread and are about 300 total).
