It will be improved. The things that are done when you enter a group
will have to be done somewhere and will still take time, but can be
done faster.

Closing a group currently takes time on big groups since we clear all
flags and re-set them (yes, this is broken).

I'm not sure if gnus-agent can help us cache NOV entries for a group,
otherwise we could do this ourself. This should probably speed up
opening groups significantly, it's the header fetches (and associated
work) which takes most of the time entering a group.
