Note in the captured warnings, we see several cases of sqlite3.ProgrammingError: SQLite objects created in a thread can only be used in that same thread. The object was created in thread id 139786115352256 and this is thread id 139786104866496., which seem to be what is causing some threads to fail, hence the test to fail.

Python 3.13 changes doc notes: "Add new dbm.sqlite3 backend, and make it the default dbm backend."
