Interrupt latency problems on MPC860

Another way to get interrupt latencies down a little is to move the
`tick()' processing to a high-priority task and have the timer interrupt
handler send an event to this task.  The tradeoff is a little more time
spent handling the timer/tick(), but now the tick() handling is
interruptible.
