as we try to disble client side keepalive we made change in
cache_acceptor_epoll.c by disabling sesion timeout chceck and shorting
this timeout:
if ((tmp_timeout - last_timeout) > 60)
to:
if ((tmp_timeout - last_timeout) > 0.1)

and it looks like it solved our problem ...

is there any problem we should be expecting on high load after this
modification?
