Well, actually there's a pretty good reason for the "port in use" behaviour: 
the TCP standard more-or-less requires it. A srchost/srcport/dsthost/dstport 
combination should not be reused until the maximum TTL has passed, because 
there may still be "old" retransmissions around. Especially the "open" packets 
are potentially dangerous.

Setting the reuse bit while you're debugging is fine, but setting it in 
general is not a very good idea...
