Locking operations in fastify routes

Hello!

I am curious about people's thoughts on approaches to handling locking operations within fastify routes. I have a typical lock use case, where I have a global resource (file) that needs to be updated one at a time in response to inbound requests (or drop the request and have the requester retry if the lock is held).

Currently I am using [proper-lockfile](https://www.npmjs.com/package/proper-lockfile) to handle this through a file lock, which works well, but I am wondering if there are any native ways of handling this in fastify that may be more performant. I have looked into [fastify-locks](https://github.com/piscinajs/fastify-locks) but was unable to get it running and unsure if it is still maintained.

Thanks for your time and this excellent project!
