I found something from wicd in my processes (see attached ps_ax.txt). So, it is possible that eth0 is configured by wicd.
I run wicd-client and press "Отключиться" ("Disconnect") button. Then I see at network applet at my lxpanel. Network interface was down for one second, button "Отключиться" ("Disconnect") was renamed to "Подключиться" ("Connect"). Then something enable interface again. Name of button in wicd-client is still "Подключиться" ("Connect"), so wicd is not know that interface was enabled. So, i think that interface was not configured by wicd at boot time or wicd has partial control at it. Something else exists and controls network interface. At past I think that it is something Debian-specific and ifupdown is part of it. But now I do not know what it is. I can only guess that wicd tries but can not disable dhcp client when disabling interface.
