>it also introduces some non-determinism that might be trouble. Also, it does seem to be the case that most big internet sites have multiple ip addresses which rotate each time a dns query is issued. Ebay has 6 for example. A dial to www.ebay.co.uk now sends 6 syns. Maybe a couple of the ip addresses manage to respond with a syn before one of them is is "chosen". The other five are reset. I'm finding it hard to convince myself that this is good behaviour.
