A bind() with sin.sin_port == 0 will return a random port in a range1024.We think this is a big win, though the bugs that are exploitable with predictable port ranges are quite difficult to play with (and rare).
Theo, Linux does likewise - and you also get a performance advantage. However your explanation misses a problem - you may randomly assign port 6000 - which is sort of a well known port for X windows
