Perhaps the difference is below the noise floor? I was focusing only on startup time by running lsprofcalltree over a script containing only "import pylab". In that context, dedent was the largest contributor to startup time (other than stuff in the stdlib and numpy) before this change. But I would imagine that that over the total time of backend_driver.py and actually doing stuff like, say, *plotting* is fairly insignificant.
