But open() doesn't work that way.  open(filename, "wb") unconditionally
clobbers filename.  That's one way to resolve the race condition, I
suppose, but not really satisfactory.

I'll take Dave's suggestion and see how tempfile does it and maybe even
use that module instead of reinventing the wheel.
