Isn't that another result of https://bugs.launchpad.net/upstart/+bug/406397

How is that supposed to work and where is that 'sshd part'?

The service will be restarted after main package upgrade. Though we have
the real problem of -upstart subpackage here: the restart should
probably be done when both main and -upstart packages are upgraded.

I guess  --no-wait for emit should be used here. Though there is
something blocking – emit waits for some action on the 'started' event
to finish and some service starting on this even has probably locked up
(most probably due to https://bugs.launchpad.net/upstart/+bug/406397 and
broken /etc/init/*.conf file (I have recently fixed those for openssh
and syslog-ng)).
