  What exactly is that cycle? Can we break one of the links with a local import?

For a separate patch: I find it weird to refer to these undefined fields (_repo 
and _path). Can we pass these into the constructor (which is currently not 
defined) and assign them there?

Can we put them in abstractfilectx if they seems generic enough? We can still 
created optimized versions in subclasses.
