[Mathieu Trudel-Lapierre <mathieu.tl@xxxxxxxxx>]

We've discussed this and my understanding was that the fix for the
issues would go in APN editor, where it's quite simple to disconnect the
interface just before activating the new context, rather than in NM
where these kinds of calls can be quite racy (or oFono where it would
mean some re-engineering of core oFono bits, which we don't want to get
into at the moment).

I'd still like to keep the network-manager task open but demoted to
Medium, or even Wishlist. I'd still like to add some extra suspenders to
at least make it easy to see the cause of the errors, and possibly
having a workaround (though one that would most likely cause unwanted
long delays in userspace if it was the only solution to fix this bug --
ie. make most of the process blocking, which would make it hard to
properly track state in userspace since there would be a few device
state transitions involved).
