[99s-extend] timeouts and slow clients in cowboy loop handler

[akonsu]

thanks!

how to implement timeout callback manually? if I had receive then I would
just use timeout clause there, but with the handler I do not know...

I have doubts about validity of my question on the erlang list.  I later
realised that there is no problem receiving messages in my handler from my
upstream process, I can do it fast enough and shove everything to the
response. my real problem is to determine if the http client is reading
fast enough from the response...
