If the timer handler is written so that its author is _positive_ it can
be interrupted, that code can enable quitting.
Actually I am not sure that this can be done safely. If the timer
handler can get run inside of a place where quitting is not allowed,
and the handler binds inhibit-quit to nil, then the result could be to
quit from a place in the main program where quitting should not
happen.
There are places that read input with inhibit-quit = t,
such as read-quoted-char, and this problem can indeed happen there.
