These traits can be leveraged to access an open LockFile for purposes like inspecting its metadata, or opening it as a File.

Importantly, these traits can't easily be misused to unlock or close a LockFile prematurely: to do so, you'd have to write unsafe code.

Hi! No rush, but do you think you might have a chance to look at this some time this month? We need it in Arti to check the age of a lock file, and to implement safe deletion for lock files.

We've had to make a fork (hopefully a temporary one!) to get this feature for now.

In case you're curious, here's how we're using it.
