Yup. I've seen this too. And it is gate_news, I've run top on a
very wide xwindow to read the full proc. name. I also don't use the
gateway, and just commented it out.
And I can see, looking at the gate_news code exactly why it will
do that, too.... The way it is currently coded, it will fork
<number-of-lists> proccesses, and _those_ will fork <number-of-lists>-1
proccesses, and _those_ will fork <number-of-lists>-2 proccesses, etc.
The last for loop in gate_news needs a sys._exit() at the end to
