I am not working on this :-)

As I see, this is only possible by one of the following approaches:
1) Converting groupinfo into a database to allow record-based locking
instead of locking the whole file. I am somewhat reluctant to do
this, because one of the things in leafnode that I like is that the
storage format is extremely simple. I would like to keep it that way.
2) Implementing a daemon which is the only program allowed to read out
and write the groupinfo file. Any other programs requesting information
or changing entries into that file would have to talk to that daemon.
This is the approach which I currently favour.

What about a small script wrapper around it or using anacron? I don't
think this functionality should be built into fetchnews itself.

If you are interested in hacking code, I can email you the latest 2.0a10.

No. Should we create one? (Actually, I like it the way it is, but others
