What

When reading output from a background task, the code checks whether the file it's reading is still the same file it started with. It now specifically detects the case where the file has been deleted (link count of zero) while still open by its file descriptor, and reports a new gone status for that case instead of treating it as a generic identity-mismatch error.

Why

This gives a clearer, more accurate signal when a background task's output file has been deleted out from under it, rather than surfacing it as a confusing mismatch error.
