TCP hanging on CLOSE?

...I had a router crash this morning, and fetchmail dropped some
connection for timeout. Now I have :

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 80 0 pern:2280 upco.es:pop CLOSE_WAIT
tcp 80 0 pern:2273 upco.es:pop CLOSE_WAIT
tcp 0 0 pern:2243 upco.es:pop CLOSE
tcp 0 0 pern:2230 upco.es:pop CLOSE
[...20 more connection]
tcp 0 1 pern:2185 upco.es:pop CLOSE
tcp 0 1 pern:2184 upco.es:pop CLOSE
tcp 0 1 pern:2183 upco.es:pop CLOSE
tcp 0 1 pern:2182 upco.es:pop CLOSE

This ones are here since this morning (it's about 10 hours)

I supposed that after some time they would be forcibly closed. Server is
pop3 daemon, I am not sure what machine but I think a SG (sendmail
says IRIS 2.0).

Linux 2.2.3 vanilla.
