Thanks Nick for the 'insight' of epoll.
Usually I'd expect an application to have a 'knowledge' of which FS were

Hi Mike,
I don't know about the inner Working of the epoll calls, so I will

I am trying to understand the behavior of bind resolver regarding a
particular issue. Let us say a resolver A sends a query to a server B.
If the response is too big, B will set the TC flag. Let's assume that
the truncated portion was NOT part of the additional section since I
