This connects with my other comment on IMAP retrieval.  But there's a
bigger problem: Gnus is by design synchronous.  You enter a group, then
wait for the summary buffer to be built.  Gnus doesn't have the concept
of "enter a buffer and let the articles come in asynchronously" and I
doubt it's possible without some multithreading support in Emacs Lisp,
which has been discussed many times but is probably far in the future
(at least a year, judging by threads in emacs-devel).  Gnus blocks on
many other operations too.
