I'm ignorant on the issue... does active timer mandate check for expiration at every timer tick? If yes, it is somewhat silly to use timer: such check would be more costly than
if(!++jiffies) jiffies_hi++;
(or similar) construct in timer int.
BTW, I always liked above thing more that any other 64 jiffy solution.
