    How would you notice if flyspell did some "behind the scenes" 
    dictionary setup ?

It might cause a lot of trouble if it had a bug of some kind, or if it
did things with processes at a time you did not expect.

Anyway, my intuition, based on many years of programming, says
that it is a bad idea for switching buffers to run a hook.
