I solved it with putting
Thread.list.each {|t| t.join(10) unless t == Thread.current}
in redmine_issue_reminder / lib / tasks / reminder.rake
behind ReminderMailer.deliver_issues_reminder(user, queries_data)
does that make sense? would be nice if somebody can confirm that - in that case we could overtake it officially here
