I think what you are seeing is that each place has it's own Console.OUT and
OUT is only flushed on newlines. The only newlines are happening at place
0, so only the OUT stream at place 0 is getting flushed.
Arguably we should be flushing OUT in all places as part of tearing down
the program execution, but I don't think we currently do that.
