I think the reason to wake up 'wake_batch' waiters is to make sure
wakers will use up 'wake_batch' tags that is just freed, because each

Hmm ... I think it's up to you to (a) explain this behavior change in
detail in the commit message and (b) to prove that this behavior change
won't cause trouble (I guess this change will cause trouble).
Thanks,
Bart.
