connection starvation problem

[xinghua_hi]

hi:

      In man epoll , a section refer to "epoll edge trigger  starvation
problem", and around to this we need to maintain a ready list instead of
read socket
until EAGAIN. but i didn't find any related solution code in nginx. In
request body read function `ngx_http_do_read_client_request_body`, it seems
that
nginx will read socket buffer until EAGAIN or has read Content-length data.
so if a client is fast enough and post data is large enough, is it possible
to 
starve other connections? SO do i miss something important? nginx how to
deal with this situation in read and write?

thanks!
