What if we can override the inner call to os.open()?
For example, io.open() could grow an additional argument "fd_opener" which
defaults to the equivalent of os.open.
Then creation mode can be expressed like this:
open(filename, 'w',
fd_opener=lambda path, mode: os.open(path, mode|os.O_CREAT)
Another use case with openat (see #12797):
open(filename,
fd_opener=lambda path, mode: os.openat(fd, path, mode)
