2.2.0-final - TCP connections hang *again*

Until 2.1.1xx (early '100s), there was a bug that resulted in processes
hanging on TCP connections. Now and then, I have hundreds of "inews -h"
processes running at the same time. Some percent of them stay forever,
connection (over the local interface) is "ESTABLISHED" from one side and
"SYN_RECV" from the other side. At one moment, IP guys fixed this and
this effect disappered.

Now, in 2.2.0-final, it is back again :-(

1939 ? S 0:00 /bin/inews -h
1942 ? S 0:00 /bin/inews -h
1945 ? S 0:00 /bin/inews -h
1949 ? S 0:00 /bin/inews -h
