Found by the depth sweep: a hook that sent a message about another node
overwrote (ONE), which AWAIT reads after believing a GONE, so the wait went
on. (DOWN) now calls the hook through (RUN) and restores (ONE).
AWAIT ended by a GONE that is handed on: works to 26 values and 21 calls
deep, then a stack error and nothing else, at both widths. Removal sweep:
node 11 or 12 removed, or the wire cut, at every step: 0 wrong. hosted
dict_hash=0x248b4edc47f4357e on all three ISAs.
