Make it faster to check for new messages and then enter a group with
new messages to see the headers. At present, when I hit 1-g to check
for new mail in one nnimap group, it sometimes takes Gnus about 10
seconds to report whether a message arrived or not (with
`nnimap-need-unselect-to-notice-new-mail' set to t). Then, if I notice
the '0' message count change to something positive, I hit enter to
select the group. Gnus then takes about ten more seconds to present a
one- or two-line Summary buffer showing the newly arrived
messages.

These nnimap groups are agentized, but I'm guessing that this slow
behavior described here involves Gnus asking the server for message
ranges and parsing the headers on new messages.

The IMAP server I use most frequently is Courier:

|   THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA
|   IDLE ACL ACL2=UNION STARTTLS] Courier-IMAP ready.

I can understand the '1-g' operation taking a while, or selecting a
group to take a while, but it's painful that both take a while and
both are necessary just to see a new header in the Summary.
