[PATCH] ui/ncurses: Periodically refresh display

One other option would be to:

 - only start the interactive UI when input is received
 - before that, we just print the petitboot logs (possibly without
   ncurses), and possibly a 'hit any key' message

The advantage of this is that the ncurses startup doesn't happen until
there is an actual terminal connected, which can be queried for its
capabilities & size.

Cheers,
