OOPS, I didn't notice you submitted the patch which did similar
about RUNTIME_DISCARD_EXIT, then I'd like to recall patch1. I
expected some review comments for remainning patch2\3\4, I will
send v2 which will both address possible review comments and
remove patch1

If you like it, you can take it into your v2 patch;)
