Tso proposes a scheme to create a lock file for each article while nntpd is receiving it. I was considering doing this, especially in connection with C-News-style NNTP batching. Haven't gotten around to doing it yet. (Locking within a multithreaded NNTP server would be cheaper.) The question is, what do you tell site B when the article it tries to offer you is being sent by site A? "Gotit" is wrong, if the A xmit fails. Blocking until the lock goes away is unnecessary delay. The best thing is to tell site B to ask again later. -- Felix Lee flee@shire.cs.psu.edu *!psuvax1!flee
