This wrapper helps ensure that the file descriptor is closed exactly once.
If you don't explicitly convert or close the FileDescriptor object, it will
close its file descriptor when it goes out of scope, and emit a
ResourceWarning.

This can safely be called multiple times, but will raise RuntimeError
if called after converting it with one of the ``to_*`` methods.
This object can also be used in a ``with`` block, to close it on
leaving the block.

raw_fd = fd.to_raw_fd()
os.write(raw_fd, b'xyz')
os.close(raw_fd)
The :class:`FileDescriptor` can't be used after calling this. The caller
is responsible for closing the file descriptor.

with fd.to_file('w') as f:
f.write('xyz')
The arguments are the same as for the builtin :func:`open` function.
The :class:`FileDescriptor` can't be used after calling this. Closing
the file object will also close the file descriptor.

This returns a standard library :func:`socket.socket` object::
with fd.to_socket() as sock:
b = sock.sendall(b'xyz')
The wrapper object can't be used after calling this. Closing the socket
object will also close the file descriptor.
