You'd also need to make sure that all the mail is stored into user's
mailbox, before firing up qmail-pop3d.

Well, I would solve the problem differently.
I'd start up from POP-before-SMTP kind of set up.
1. fetchmail uses database of users "known to be present".
2. This database gets "aged" every now and then from a cron script.
3. After a successful POP3 connection, you'd write "user xxx
present" into the database.
A user would first connect by POP3 and learn that there's no new
mail; then fetchmail would start up, download the e-mails also for
this user (because his name is in the database); next POP3
session would bring the user all his mails. - Some ten minutes
after his last POP3 session, his name would get deleted from the
database and mail would stay at the main server.
If you can tune
1. how often fetchmail pulls
2. how often user pop3-connects
3. how often the database gets aged
you can close the window (after last pop3 session, fetchmail might
pick up user's mail once more, leaving it in your queue).
