    *) Bugfix: in SSI parsing.

    *) Bugfix: if remote SSI subrequest was used, then posterior local file
       subrequest might transferred to client in wrong order.

    *) Bugfix: large SSI inclusions buffered in temporary files were
       truncated.

    *) Bugfix: the perl $$ variable value in ngx_http_perl_module was equal
       to the master process identification number.
