OTOH sometimes when I enter groups with large messages, the summary
buffer doesn't match the article buffer contents sometimes, and I have
been suspecting the backlog and/or asynchronous prefetching for that
(but never been able to track down exactly what is happening).

the bug and fix it.</optimist>
