I think there may be something more going on here? :(

For reference net-next-2024-08-27--12-00 is when this fix got queued:

https://netdev.bots.linux.dev/contest.html?executor=vmksft-nf-dbg&test=nft-queue-sh

Since then we still see occasional flakes. But take a look at 
the runtime. If it's happy the test case takes under a minute.
When it's unhappy it times out (after 5 minutes). I'll increase
the timeout to 10 minutes, but 1min vs 5min feels like it may
be getting stuck rather than being slow..
