nginx-0.1.37-RELEASE import

    *) 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.
