I don't think you're going to find a good solution as long as your client is
running from a CGI.  The way to reduce load on an IMAP4 server is to make
fewer connections and open fewer mailboxes (generally speaking.  Different
IMAP4 servers have different performance characteristics; you should learn
about yours and avoid the requests it specifically cannot satisfy efficiently).
