FWIW, the problem seems that `linum-mode' indirectly changes the value
of windows' use_time so the value returned by `get-lru-window' is messy.
use_time is updated by `select-window', hence a potential culprit is
`walk-windows' which is used by `linum-mode'.  Could you try to find out
whether my guess is correct and/or where and how use_time is set when
`linum-mode' is active?

Thanks, martin
