func Sources() map[string][]byte

Sources returns independent copies of the fixed compiler-owned support files. Callers cannot supply paths or register additional native authority.

func TryLock(root *os.Root, path string) (*os.File, error)

TryLock acquires a fresh open-file description for a stable, regular lock file. Closing the returned descriptor releases the lock; the name is kept.
