Claude	2cf75febdc	timer: sleep(duration) via min-heap of (deadline, pid) ... Adds a BinaryHeap of timer entries on SchedulerState. sleep() inserts an entry and parks; schedule_loop pops due entries each iteration and unparks them. When the run queue is empty but timers are pending, the OS thread sleeps until the soonest deadline. Single-threaded only; thread::sleep is fine because no other thread can wake us. The IO thread coming next will need a Condvar or pipe wakeup to break this OS-sleep early.	2026-05-22 05:22:55 +00:00
