Re: need delay while key not pressed

Your code enters a hard loop where it delays forever.  Nothing changes any
variable that would help the loop to end, so your OS is helpfully telling
you there's a problem.

SDL can only change the 'event' variable if you give it control, say, in a
function like SDL_PollEvent().  `event.key.keysym.scancode` will not
magically change on its own.  Use SDL_PollEvent() in your delay loop and
then you'll be getting somewhere.
