@sergey-miryanov @hugovk My first backport; apologies if I've missed something. Left as draft, since it's waiting for 3.15.1 |

Manual backport of #155828, @miss-islington hit a conflict in #155828 (comment)
3.15 does not have
stats_mutex(#151766 wasn't backported), so the sequence counter update there is applied without thePyMutex_Lock()/PyMutex_Unlock()pair. The rest went fine.(cherry picked from commit 5fecd44)
Disclosure: used Claude Fable 5.1 to apply it (mere bookkeeping.)
