[Dovecot] Return (revenge?) of the "pop-lock".

[Christian Balzer]

Hello,

The users here have been migrated to the new mail system with dovecot
0.99.10.5 (Debian package) on the backends. Storage is maildir, only
pop3 access for now.
I see very seldom occurrences (compared to the session wide pop lock 
of qpopper on the old system) like this: 
---
Jun 16 14:35:52 mb01 pop3(user at gol.com): 
Timeout while waiting for release of exclusive fcntl() lock for index file 
/mail/spool/mb01/9ef/f73/af.user/.INBOX/.imap.index
---
These are people with slow connections and at least one large mail in
the box, with their client aborting w/o terminating the session properly.

I presume the timeout for this is hardcoded, as all the config 
parameters for timeouts are mbox related, rite?

Regards,

Christian Balzer
