nnrss often hangs recent CVS Emacs

["Andrew A. Raines" <aaraines@pobox.com>]

I switched a few days ago to Emacs 21.3.50 from 21.3.1.
Gnus seems to like the newer environment.  Things seem
much smoother and updates to the group buffer when
fetching mail and news are quicker.

nnrss, however, works intermittently.  Often when updating
a group, Emacs will hang indefinitely.  I mean _really_
hang -- if I have an external process going in the
background (like mplayer through EMMS), the track will
pause, and if I let Gnus run through its course (something
eventually times out I guess), my erc sessions get
disconnected.

I'd say about 1 out of 5 times the updates to the nnrss
groups are speedy and pleasant.  I scored my RSS groups
really low though because it's frustrating to constantly
C-g.  When I'm desperate for an update I M-g on the actual
group, which for some reason hangs less often.

I know the nnrss code is in flux right now, so if I have
to live with this issue for a while I understand; I didn't
want it to go unreported though.  Or, it could be a bug
with Emacs.  Does the newer Emacs use a different method
for fetching URLs than stable versions?
