I've just switched from using restarts to reloads a week ago so we'll
see if it crops up ;)

My understanding of the issue (from personal experience) is that a
restart didn't always kill the old daemon before starting the new one,
resulting in two (or more, after several restarts) daemons running and
writing to the same status files. Since a reload doesn't spawn a new
daemon process, the problem shouldn't occur. It seems I might not have a
complete understanding...
