In the old-days Newsgroup-names didn't contain minus-signs.
Now they do.
So I hacked the good-old NTTP 'handler', [based on rfc..].
But now, sometimes it hangs.  Often after the first fetch.

When I asked: list article-header-numbers in comp.sys.raspberry-pi,
containing "onta" in <Subject>, it hang, if it's already done a fetch.

lsof | grep <pid>
  shows the 2 lines:--
 22380   root   29u  IPv4  391647 \
  TCP 10.208.223.203:41160->78.46.70.116:nntp (ESTABLISHED)
 22380   root   30u  IPv4  391655 \
 TCP 10.208.223.203:41162->78.46.70.116:nntp (ESTABLISHED)

Does this mean that I had 2 connections to 78.46.70.116:nntp,
when it hung ?

Shouldn't the 1st connection have closed, since I only 'called'
the second fetch, after I saw that the 1st had arrived.

Perhaps the NNTP-server [eternal september] doesn't allow D.O.S.-like
multiple connections?

==TIA.
