Thanks for clarifying. I understood you to be intending to block the
patches until they were converted to an async interface, which is not
what Zinc's about. Seeing as you're just curious about future
directions, that seems much more tenable.

I am extremely grateful for a good portion of your reviews indeed. As
I mentioned earlier, much is very useful. But in other places, I fear
you're steering this in a direction I really am hesitant to go.

And indeed all of these concerns I've been pretty amenable to, and
continue to do so. What I'm commenting on are things outside of these.

Apologies, and duly noted. I'll give you the benefit of the doubt.
