[SDL] Framerate independence?

[Jonathan B.]

Oh wow.  Please *do not* do it like this.  This is a busy wait which 
will attempt to eat 100% of your CPU doing nothing until the appropriate 
time.  It is really horrible for any multitasking OS.

It is much better to use SDL_Delay as mentioned on the usingtimers.html 
page.
