[Dovecot] I/O leak

[Jim Horner]

I upgraded from rc12 to rc14 last night... sifting through the logs I noticed 
the following. I point this out since it appears dovecot is in high gear 
bug-fix mode. This issue is not big for me; I rarely stop dovecot. My init.d 
script for dovecot is basically

stop)
    killall dovecot imap-login

I am guessing there might be a more graceful way to stop dovecot? Or rc14 
fixed this? I see in rc14 changelog:

 - rc13 crashed if client disconnected while IDLEing

but only user1 was IDLE.
