[Dovecot] BUG REPORT - Stops logging after sleep

[Bruce Bodger]

Version: dovecot --version:  1.0.0
OS: OS X - 10.4.9
Architecture: G5 Dual/1.8Ghz

Had a fairly normal time correction last night:
May  9 20:56:56 G518X2 ntpd[219]: time set -1.212733 s

Which dovecot duly noted:
May  9 20:56:56 G518X2 dovecot: auth(default): Time just moved  
backwards by 1 seconds. I'll sleep now until we're back in present.

This morning all of the dovecot processes are running fine but  
dovecot has stopped logging.  (I have modified nothing in  
dovecot.conf relative to logging: dovecot logs to syslog using the  
"mail" syslog_facility.)

ps -aux | grep dovecot

I am starting dovecot via OS X's launchdaemon facility thus the "-F"  
command line switch requirement.

Sending a "kill -HUP" to the process did not get it to start logging.
Sending a "Kill -9" to the process forced a restart and logging began  
again.

ps -aux | grep dovecot

Before posting this bug I compared v1.0.0's /src/lib/ioloop.c to that  
in the nightly snapshot and saw no adjustments in, what I presumed to  
be, the relevant portion of the code.

Output of "dovecot -n"
