How do you start nnrpd? There are at least three ways I've used:
- have innd do it if non-peer or MODE READER
- innd on an alternate port and nnrpd -D
- innd on an alternate port and xinetd starts

I have never had a problem with the first two reaping zombies. Versions 
and patches would be nice as well.
