Hm... that sounds too invasive to be honest. The Context users are
low-level loaders who don't know how to bail out properly. That would
probably mean a lot of exception throwing, plus it would leave data in
an undefined state if bailing out happens (not sure if this would be a
huge problem in this particular situation but it could well be).

Come to think of it, I guess I'll have to implement a suspend/resume
style signalling between the two threads in onPause() and
onDrawFrame(). Technically just a couple of lines of code, but I
don't like having that kind of code if I can avoid it, it tends to be
subtle and easy to mess up inadvertently in the future. It would be
good if this was encapsulated in a platform API.
