Checkpoints are an optimisation -- so is the GC thread. I'm perfectly
happy with the idea that killing the GC thread also stops checkpoints
from happening.

I was thinking of doing it during a normal write to the file, or during
garbage collection of a node belonging to the file.

But I think we can play with ideas on _when_ to call this once you've
actually implemented the functions which does it :)
