Grr, bring backs my memory of ctx being the most important!

In order of segregation, I think of it as device+context as being the
outer container (a user isn't meant to escape their context). The
timelines and engines they use are all contained within their context.

But what we call ctx here isn't really context, but timeline; how about
if we switch to the fence=%llx:%d representation we've mostly settled on
for the debug messages?
