Hi Michal,

I'm back from vacation. I owe you an apology I was entirely too
prickly on this thread, and the vacation cool-off-time was much
needed.

I come back to see that Alex has found a trove of low hanging fruit to
speed up ZONE_DEVICE init and ditch most of the complication I was
pushing. I'll let him chime in on the direction he wants to take this.
