Why does Gnus hang for a long time when posting?
================================================
David Lawrence <tale@uunet.uu.net> explains:
The problem is almost always interaction between NNTP and C News.
NNTP POST asks C News's `inews' to not background itself but
rather hang around and give its exit status so it knows whether
the post was successful. (That wait will on some systems not
return the exit status of the waited for job is a different sort
of problem.) It ends up taking a long time because `inews' is
calling `relaynews', which often waits for another `relaynews' to
free the lock on the news system so it can file the article.
My preferred solution is to change `inews' to not call
`relaynews', but rather use `newsspool'. This loses some
error-catching functionality, but is for the most part safe as
`inews' will detect a lot of the errors on its own. The C News
folks have sped up `inews', too, so speed should look better to
most folks as that update propagates around.
