I'm not convinced this is good enough, since a user could conceivably have
two sepperate webmail sessions on the same system (imagine two windows
open to the same webserver, browsing different mailboxes).  Now which
session knows the state of the IMAP connection?

You need something to juggle the possibility that there are multiple
concurrent web accesses for a given userid, and just storing a single
socket in the selected state isn't good enough.
