# We want the call to Disconnect to reach Idle before the call to
# g_socket_client_connect_to_host(), which connects to this Python process,
# completes. I tried making the Twisted infrastructure stop calling
# .accept() but that doesn't seem to have any effect.
#
# But! All is not lost! Making a blocking call to Disconnect() does the
# job, because we block in libdbus and Twisted doesn't get a chance to poll
# the listening socket until Disconnect() returns.
conn.Disconnect()
# The bug was that Idle would not try to cancel the in-progress connection
# attempt. It worked when the connection was blocked on TLS verification
# (see disconnect-during-cert-verification.py) because closing that channel
# (as a side-effect of disconnecting) caused the TCP connection attempt to
# fail, but didn't work in this case.
