Intermittently failing test

Commencez par tests/test_autosave.py::test_context_manager_thread_safety et reproduisez l'échec de Windows CI de l'exécution liée. Comparez le comportement lié à Autosave avec epicsdbbuilder issue #32 et PR #177 ; le travail est considéré comme terminé lorsque la cause intermittente est identifiée, que le test réussit de manière fiable dans CI et qu'il est confirmé que l'échec ne se reproduit plus.

There seems to be an intermittent failing test, introduced in the Autosave feature. Here's the failure stack from the last failed run:

The issue appears to be coming from epicsdbbuilder, which is why I've raised this issue there.

I've attempted to investigate this issue in CI in PR #177 , but have been unable to recreate it so far.
