I should explain more precisely: it's so that if packets from
the old connection come straggling in after wandering around
the 'net for a while they don't interfere with the new
connection. If you don't allow a port to be re-used for longer
than the maximum time it could take for a packet to get from A
to B, then that's not a problem. I have a vague recollection
that there was a way that reusing a port immediately could be a
security problem, but I can't figure out what the scenario
would be.
