Thanks. Out of interest, 64 bit or 32 bit (system and Python)?
I wonder if ctypes got significantly faster in Python 3.x, or what's
going on here. Python 3 is significantly faster in my tests too --
noticeable on Linux.

Yeah, that's over too quickly for a real test, isn't it? I'm already
creating a 230MB dir, but maybe I need to add more, smaller files.
Easy to tweak with the NUM_FILES and NUM_DIRS constants (though you'll
need to delete your current "benchtree" dir so it recreates it. Maybe
I should bump up the defaults too.
