myfunc.post(.. and post_event take special params like delay but that would prevent the a normal delay parameter from being used.
So we should make it __task_delay. Same for flush_immediately, and adding priority as an option now too.
Then after that improvement, lets start using __task_priority in the reindex command, so they can run at a lower priority and not interfere with normal tasks.
