That's suspiciously close to the core sprint. Since the -S time stayed roughly the same I suspect that either a new module was added to the startup sequence or one of the (too many) modules already involved grew a lot. My money is on a new module. Using `python -v -c pass` on a Python built from the Sept. 9 tree and one built from Sept. 15, it shouldn't be too hard to figure out which new module(s).
