Without this, if the size of refs_file at that point is ever an exact
multiple of BUFSIZ, then an EIO or ENOSPC error on the final write would
not be diagnosed.
It's not worth worrying about EPIPE here.
Although theoretically possible that someone kill this process
with a manual SIGPIPE, it's not at all likely.
