Wouldn't expect to see such linear progression if that were the case. Steps, over a relatively long period of time, would be the likely pattern, no? Same goes for some other process fighting for resources. Every iteration requiring what appears to be a fairly constant increase in execution time (2-5ms on every iteration) seems an unlikely pattern unless the two processes are linked in some way, I would think.
