Thanks for the review Christoph. I think I should be able to make all
the requested changes in the next week or two.

I sort of follow this. I can try to work something up but it will
probably take me a few iterations to get it to where you want it. So,
roughly, we'd create a passthrough_q in core with the controller's IO
tagset and then cleanup the fabrics hosts to use that instead of each
independently creating their connect_q?

Though, I don't understand how this relates to the host xarray stuff
that Sagi mentioned...
