*) Change: now the "\n" is added to the end of the "nginx.pid" file.
*) Bugfix: the responses may be transferred not completely, if many
parts or the big parts were included by SSI.
*) Bugfix: if all backends had returned the 404 reponse and the
"http_404" parameter of the "proxy_next_upstream" or
"fastcgi_next_upstream" directives was used, then nginx started to
request all backends again.
