It does not work.

The effect is still the same.
A sshd -d yields:
Connection closed by remote host.
debug1: closing all channels
debug1: channel_free: channel 0: server-session, nchannels 1
debug1: channel_free: channel 0: dettaching channel user
debug1: session_by_channel: session 0 channel 0
debug1: session_close_by_channel: channel 0 kill 18299
Closing connection to

Following the code in session.c, session_close_by_channel with
s->pid != 0 will "notify child, delay session cleanup".
However, session_close() is never called (it would be seen due to
 debug("session_close: session %d pid %d", s->self, s->pid))
and therefore it seems that session_pty_cleanup(s) (finally calling
the record_logout() function) is never called.
