I'm afraid you did. However, when really bad things have happened to
your groupinfo, let your users know so they can reset their .newsrc or
use "show read articles" to get all of them just in case.

I may also have had bad tea in my cup when writing any single line of
code, but I know for sure leafnode cannot handle SIGKILL. Nothing in
user-space can.

Sort of, 1.9.21 is not exactly current any more, later versions try
harder to keep the groupinfo file up to date.

I advise that noone runs a version older than 1.9.27, and if that gives
some headaches, the upcoming 1.9.30 should fix them.

Nah, I'll rather not smoke at all.
