I think simply doing it in the process suffices, but yes to some extents
iptables (the Linux-2.4 ipfw/ipchains) can do it for you by round-robin

The first problem is that you must know that the object is being
written. Once you know this the rest is quite trivial. An I imagine that
it is quite trivial to know that the object is currently being open for
