According to the change log:
20090305
Bugfix: in the "new queue manager", the _destination_rate_delay
code needed to postpone the job scheduler updates after
delivery completion, otherwise the scheduler could loop on
blocked jobs. Victor & Wietse. File: qmgr/qmgr_entry.c,
qmgr/qmgr_queue.c, qmgr/qmgr_job.c.
This fix was released with Postfix 2.5 Patch 07.
