Pterodactyl Gnus v0.83
XEmacs 21.1 (patch 3) "Acadia" [Lucid] (sparc-sun-solaris2.5.1) of Sun Oct 10 1999 on bolzano
200 pfaff.ethz.ch DNEWS Version 4.7m, S0, posting OK 

While trying to determine why XEmacs is sucking up so much CPU
sometimes, I noticed the following:

Try reading NEWS with Gnus for a while with async prefetch enabled,
then type M-x edit-itimers.
I have about 400 itimers of the type..

"itimer-<62>"           0.1       nil   gnus-async-prefetch yes    ("nntp+sunsite.auc.dk:emacs.ding" 14229 #<killed buffer>)

somehow the idle timers for prefetching are not being deleted.
