Generally it should. However, os.get_terminal_size is unnecessarily limited to
the standard handles with a hard-coded mapping 0 => StandardInput, 1 =>
StandardOutput, and 2 => StandardError, and otherwise raises ValueError.
Example failure:
>>> fd = os.open('conout$', os.O_RDWR)
>>> os.isatty(fd)
True
>>> os.get_terminal_size(fd)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: bad file descriptor
There is no need to involve the standard handles. It should call
_get_osfhandle(fd).
