runtime: selectgo need not lock all the channels involved in the select #41948
Description
i read the select function:
func selectgo(cas0 *scase, order0 *uint16, ncases int) (int, bool) {

// lock all the channels involved in the select
sellock(scases, lockorder)
}
why we should lock all the channels?
i think lock one by one when loop may be better , because it will quickly
