[Bug 1936881] Re: fix channel_termination_timeout

[Sergio Durigan Junior]

Thanks, Seyeong and Lucas.

Seyeong, no problem at all, and thanks for the quick follow-up!  I will
wait until you have news from the customer before we proceed with the
upload.

FWIW, I can't check the patch right now because the URL is 503'ing here
(internal LP problem, most likely).  But I remember that the patch was
pretty much OK aside from DEP-3 issue, so if that's been fixed then it
should be good to go.

Cheers.
