the call to redisplay makes startup unresponsive for few seconds during startup #48

I was wondering why during startup there was a noticeable pause just after enabling modeline-mode. Typically when I startup my emacs it's immediately responsive. I realized that the function mini-modeline--enable calls redisplay and I believe this causes this delay.

After advising the modeline-mode, temporarily setting redisplay to ignore during its evaluation, the problem was gone.

Would you like to provide a PR for that?

@kiennq sure. However, what was the original intent of redisplay? I'm concerned that removing it might have unintended side-effects.
