--- Comment #2 from Francesco Vincenti (franci.vi@tiscali.it) ---
Hello Oliver,
thanks for your fast answer. Looking better at the code, the presence of
identical spin-lock in both contexts, producer-only-appends discipline,
re-verification of desc->length under the lock prevents data corruption.
Best Regards,
Francesco
