Your stack trace shows that this is due to the latest patch to
back-bdb/cache.c, rev 1.175. If you revert that patch this deadlock will go

OK. This isn't hitting me in production (to my knowledge at least), only
as "please test RE24." So I'll wait for the next "please test RE24" and
give it another go...I'm sleeping until then. Thanks.

Go ahead and test the patch in HEAD, thanks.

The HEAD patch causes a deadlock when bdb_cache_delete_cleanup() is called by bdb_cache_lru_purge(), as the latter already has the entryinfo locked.
