In .pick_next, we count current object's timeslice and pick the next
avaiable one. The policy is
1) get the first item in runqueue firstly
2) if object picked has no time_cycles, replenish it pick this one
3) At least take one idle sched object if we have no runnable object
after step 1) and 2)
In .wake, we start the tick if we have more than one active
thread_object in runqueue. In .sleep, stop the tick timer if necessary.
