LGTM but what happens when I pass e.g. { stdin: -42 }? validateInt32() won't reject it.

LGTM but what happens when I pass e.g. { stdin: -42 }? validateInt32() won't reject it.

The third argument to validateInt32(stdin, 'options.stdin', 0); causes negative values to be rejected. Invalid file descriptors in general throw an exception: Error: UVWASI_EBADF, uvwasi_init
