I don't see that behaviour. For me, I don't get any FocusGained/Lost
Message in GTK-Gvim 7.3.315
I don't even know, whether this is supposed to be triggered in the
terminal at least it doesn't trigger for me in an urxvt terminal. Ah,
the help says, it only triggers in certain terminals. May be xterm, no
doesn't work there either.
