* Use sleepthread in RPC loop * Keep a pointer to current IOP thread * Implement IOP thread scheduling based on priority And implement DelayThread as an actual delay. * Run IOP flat out * Use information from scheduler in wait_run_iop * Lock sif mutex in set_rpc_queue * always use kernel dispatch with wait_run * Loop in dispatch until no thread is ready * Use timestamp for next wakeup instead of duration * Wrap IOP thread entrypoints for safety Libco threads are not supposed to return from their entrypoint * Use a queue for IOP thread wakeups from EE thread
