The POP3 RFC states that operations such as DELEte a message will become 
"final" after issuing a "QUIT" command. If connection breaks, no change is 
made to the mailbox.

For having multiple concurrent POP3 access to a mailbox a complete 
transaction based model including rollbacks would be needed to implement 
proper POP3. I don't think anybody wants to improve pop3d to accomplish 
that ;-)
