The file's size is stored in FileSessionSlot and retrieved when the game calls GetSize. However, it is not updated when the file is written to, which can possibly change the file size. Therefore, this can cause GetSize to return incorrect results.
Keeps the return type consistent with the function name. While we're at
it, we can also reduce the amount of boilerplate involved with handling
these by using structured bindings.
This reduces the boilerplate that services have to write out the current thread explicitly. Using current thread instead of client thread is also semantically incorrect, and will be a problem when we implement multicore (at which time there will be multiple current threads)
