It looks like open() ignores O_TMPFILE (0o20000000) on old Linux kernels. Test on Linux 3.2:

>>> fd=os.open("/tmp", os.O_RDWR | O_TMPFILE, 0o600)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 21] Is a directory: '/tmp'

>>> fd=os.open("/tmp", os.O_RDWR | os.O_DIRECTORY, 0o600)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 21] Is a directory: '/tmp'

So we should catch OSError(21, "Is a directory: '/tmp'") and fallback to the current implementation (random name, unlink), and remember that the kernel version is too old.
