Try adding:
/usr/local/bin/setlock -nx Maildir/.poplock
between checkpassword and qmail-pop3d in your tcpserver command line. For example:
tcpserver 0 pop-3 qmail-popup your.mail.host /bin/checkpassword /usr/local/bin/setlock
-nx Maildir/.poplock
qmail-pop3d Maildir &
This will limit each POP3 user to only one session at a time.
