The amount of work items processed by unit of time does not seem to be a straight line: http://www.freehackers.org/~tnagy/runtimefutures2.png . Out of curiosity, what is the "threadreferences" for?

The source file for the example is in: http://www.freehackers.org/~tnagy/futurestest3.py The diagram was created by: http://www.freehackers.org/~tnagy/futurestest3.plot

You're test code does 50,000,000 of list appends. I suspect your benchmark is telling you more about the behavior of large lists than the overhead of the futures module. You should retry that experiment with the list pre-allocated. Beyond that, the curve in that line is not exactly a large amount of variance from a straight line.
