These days, I am studying the nginx source code..

I think this code is very beautiful, and fully modulized.. BUT so it is difficult to follow the code.-_-;

BTW, In struct ngx_event_s, there is ‘unsigned instance:1;’..

I can’t understand how can the nginx detect the stale events using it.-_-;

Could you please explain the detection mechanism or give me a hint?
