we'd try to read one record afterward (would block, because zero are in
there). I think you still need a `if (nRead == 0) goto outer_loop;` or similar
before checking the `inputRecord`.
We shouldn't continue with the current iteration of the outer loop (i.e. we
shouldn't call `ReadFile`), because we know that the console doesn't have any
pending events - we should wait for new ones.
