There's a race condition in `remove()` as the lockfile is removed after releasing the lock, which is a problem when another process acquires a write lock during deletion. Also simplify life a bit in multiprocessing when a file is possibly removed multiple times, which currently is an error on the second deletion, so the proposed fix is to make remove(...) idempotent and not error when deleting non-existing cache entries. Don't tests for existence of lockfile, cause windows/linux behavior is different |
