This SDK isn't thread-safe (or even multi-process safe) because of OPTIONS cache

This SDK is crashing some of my build agents occasionally with this error:
[Errno 13] Permission denied: '/Users/USER_NAME/.azure-devops/python-sdk/cache/options.json'

Based on reading the code, it appears to be coming from here:
https://github.com/microsoft/azure-devops-python-api/blob/dev/azure-devops/azure/devops/_file_cache.py

This code doesn't appear to be at all thread, or even process, safe, as it just asserts handles to the file.
If it can't be made thread/process safe, some option to just not use the cache at all, and just fetch it directly when needed for the connection would work. As is now, I've had to implement a machine level mutex and lock all my calls to this API behind it, which is horribly inefficient, but I can't have my builds crashing with random IO errors.

azure-devops/azure/devops/_file_cache.py から始め、SDK 接続中に options.json がどのように開かれ、更新されるかを追跡します。可能であれば同時アクセスによる障害を再現し、その後、キャッシュをスレッドおよびプロセスに対して安全にできるか、または無効時にバイパスできるかを判断します。ビルドエージェントによる同時使用で報告された権限エラーが発生しなくなり、選択した動作が文書化されれば完了です。
