Ok, I'll drop it in v2.

I ran my patch with your delta in the same guest and it holds up well.
No hang and no "stalled" warning (even though the remote read timed out
a lot during the loop).

Do you want the delta in v2? I can carry it as a separate patch from you
or fold it into mine, whatever you prefer.

Thanks!
