Right you are. (I just wanted to keep this as simple as possible for a 
starter.)

You simply could use a sleep in the timer loop,. This would be arch 
independent out of the box. But it would impose accumulative delays 
depending on the CPU performance.

An more advanced timer implementation would use arch depending OS-based 
timers. This would allow for a much more exact timing.
