An analysis of what happened was circulated a few days ago and now
published:
<https://wikitech.wikimedia.org/view/TranslationNotifications_issues_2012-12>
It's fairly technical but it's supposed to help improve for the future,
although so far it wasn't acted upon: «TL;DR: Changes in MW core exposed
a bug in TranslationNotifications. The same bug is also present in other
extensions. Many people participated in preventing further damage and
fixing the issue. More work remains to be done.»
We still don't know if the translation notifications should now work or
what's going to happen to the job queue, nor how/if todays' jobqueue
disaster
(

) may impact it.
