Backing files aren't that interesting indeed, but I think there could be
cases where two BDSes refer to the same parent BDS. For example think of
the read-only qcow2 snapshot BDS that we've been talking about before.
So it would have to be more like one AioContext per connected component
in the BDS graph, if one per BDS doesn't work (why doesn't it?)
