Does this trigger "autolearn=unavailable", which I see from time to time in the X-Spam-Status header?
No, unavailable will explicitly not happen when lock contention is the problem, as that results in "failed".
Unavailable is a catch-all error state that only gets applied when no other well defined action occured.
To quote Theo in the thread "autolearn=unavailable ... ?" from Mon, 29 Nov 2004:

Has some information, but "unavailable" means "run with -D and it'll tell you". :)
