Whenever the time slice or the process needs I/O operation or is getting blocked then an interrupt (TRAP) is generated, and the action is taken accordingly. Have a look at the task_struct structure in kernel/sched.c , that should give some insight.
i.e. process (0).

AFAIK process(0) is idle task, which is continously run whenever there is no process in the ready queue. At this point of time even scheduler is not run. It gets invoked only when an interrupt has occured.
