I just learned today that you can use MainThreadNeverDestroyed (and drop your main thread assertion above).

This name seems wrong. If something says "BySession", then I'd expect the session to be the HashMap key, not the value.
Maybe this could be named something like: "directorySessions" or "sessionForDirectory"

We're supposed to use PRIu64, not %llu to print 64bit integers to be friendly to Linux ports. Looks like this code may not build on Linux but I think it I still good practice.

Changed to sessionForDirectory.
