Nack. Writing to the known_hosts file directly is unsafe. Please use mkstemp() (with umask set appropriately) to create a new temporary file. Then you can rename() the file once it's complete, which is effectively an atomic action on the filesystem (existing applications will keep their pointer to the old file safely until they close it and reopen the new one).
