Is this meant to be applied or just for reference?

Maybe we can make a proper test case out of it that runs during make
check? Would probably require that the json-c dependency is dropped,
though. Maybe we should rewrite it in Python, as we already have QMP
bindings for that (and there are already tests that use them).
