The series contains a patch that reduces the coroutine stack size, so I

didn't manage to).
Ah, I see. I suspect the clang build (since it has the sanitizer
enabled) is a worst-case for stack usage.
Is it possible for a guest to issue a sufficiently large
request that it blows the stack, or is that capped
somehow?

If the qtest can blow the stack, so can a guest. In practice it does not
happen that guests send requests so large, but mum's the word on a
naughty guest.
