+Cmd.Wait(): handle EINTR return code from os.Process.Wait().
+
+This is probably not actually the correct fix; most likely
+os.Process.Wait() itself should be fixed to retry on EINTR so that it
+never leaks out of that function. But if we're going to patch a
+particular module, it's safer to patch a higher-level one like os/exec
+rather than the os module itself.
