Does flushing some times get "out of sync"?

[unhammer]

failing sanity-tests run about one hour apart give

exit code 1: .cat-fra: expected 'pour', got 'chaud' (for input: per)
exit code 1: ...................cat-fra: expected 'pour', got 'Éternels' (for input: per)
exit code 1: ............................................................cat-fra: expected 'pour', got '*carcater' (for input: per)
exit code 1:
exit code 1: ........................................................cat-fra: expected 'pour', got 'boulangerie' (for input: per)
exit code 1:
exit code 1: ..........................................cat-fra: expected 'pour', got 'relâcher' (for input: per)
exit code 1: .......................cat-fra: expected 'pour', got '*Cotilló' (for input: per)
exit code 1: ............cat-fra: expected 'pour', got 'rainure' (for input: per)
exit code 1: .................................................cat-fra: expected 'pour', got 'approuvez' (for input: per)

as if the output of sending "per" into apy's cat-fra was from the input of an earlier request.

(That seems quite bad)

It definitely still happens. Currently getting swe-nno: expected 'kva', got 'mitt *sdk-baserte tillegg kan ikkje vert oppgradert' (for input: vad) errors from the hourly selftest.

A solution is to add a nonce to each request sent through the backend pipe. If it doesn't come out with the same nonce, restart that pipe and try again.
