There are some fun potential interactions in there in code I haven't
looked at in a long time. I'll resist the urge to dive in and hack
something together, since VM systems have a way of being tricky in
unexpected places.

useful depends rather heavily on the devices on the bus, obviously.

I think you're trying to over-complexify the problem. All

No silly route commands, no forcing of ARP. Just add t

which will hold vm_object_sync out at the correct place.
But that's *adding* Giant, which seems li

If that's not what it looks like, you're not seeing this problem.
The best choice at that point would be to type "call doadump" at the
DDB prompt to get a kernel dump (going through doadump seems to be
the most reliable way to get a usable dump, at least for me).
