My Sherlock-omatic response is that it has to do with the relative sizes
of the group (emacs.help is probably an order of magnitude larger than
emacs.gnus.general), which would indicate some sort of caching issue:
for some reason Gnus is rebuilding something it shouldn't be rebuilding
when you open emacs.help.

How's that for useless advice?
