An operating system is provided that employs a nano-kernel and that reduces the number of times of revocation of a scheduler without impairing operation of a system incorporating the operating system. Each time a context switch occurs to switch from one to another thread, the operating system records the history of the context switch. When a scheduler that controls the sequence of execution of threads is invoked, a queue managed by the scheduler is updated tracking back the recorded history.
