See the following gist: https://gist.github.com/japhb/40772099ed24e20ec2c37c06f434594b (If you run that at the command line, you'll probably want to pipe it to `head -30` or so; it will output a lot of lines very quickly!) Essentially it appears that unlike the friendly one-at-a-time behavior of .act, react/whenever will try to exhaust all the emits from an unbounded supply *before* delivering any of them to the whenever code -- which makes it awfully hard to have the whenever tell the supply when to stop.
