An alternative version to [1], based on Tvrtko's suggestion from [2]. I tested this for Nouveau. Works.
I'm having, however, bigger problems properly porting the unit tests and have seen various explosions. In the process I noticed that some things in the unit tests aren't right and a bit of a larger rework will be necessary (for example, the timedout job callback must signal the timedout fence, remove it from the list and so on). Anyways. Please comment on the general idea. @Tvrtko: As briefly brainstormed about on IRC, if you'd be willing to take care of the unit tests patch, I could remove that one (and, maaaaybe, the warning print patch) from the series and we could merge this RFC's successor version %N once it's ready.
