Can you suspend whilst waiting? I.e. have you looked at hrtimers? Then you can 
pretty much wait for however long you want. If you need to start very shortly 
after the timer expires, regardless of the load etc, you should probably have 
a look at the rt-patch series.

Btw, why do you need to wait for 2 whole ticks? And, have you condisdered the 
consequences of this code in a tickless kernel?
