Hi Denis,

I have mixed some stuff concerning GIOChannels...

The set_close_on_unref() from gatutil.c is done for ppp_net interface 
GIOChannel.
It has nothing to do with the physical layer.

However, we do also:
     - set_close_on_unref(TRUE) into example/emulator.c
     - set_close_on_unref(FALSE) into plugins/dun_gw.c

So after the client send ATH0, the connection is removed and emulator 
should be unregistered and removed but it is not the case.

That's why I assume unregistration of the emulator is bound to the way 
PPP session is ended e.g.
normally ---> ppp_ipcpdown_notify()
forced ---> ATH0
