I'm reasonably sure it was stuck - the reductions stayed the same for at
least 30s with that message in the queue.

There didn't appear to be a huge number of outstanding log dumping jobs
that were all slowly making progress - just the one sitting there (for a
long time - more than a few minutes) waiting for a reply from
disk_log_server while the disk_log_server wasn't consuming its message
queue.
