I once wrote a locking wrapper around the shelve module so I could use it as a thread- and multiprocess-safe key-value cache (including a wrapper around the requests modules `get()` to transparently cache/validate http resources according to headers): https://github.com/cristoper/shelfcache https://github.com/cristoper/shelfcache It works despite some cross-platform issues (flock and macos's version of gdbm interacting to create a deadlock), but if I were to do again I would just use sqlite (which Python's standard library has an interface for).
