Currently I want to replace ngx_http_rewrite_module with
ngx_http_script_module only. I want to remove the "rewrite" directive,
disable all static directives inside the "if" blocks, and leave only
assignments, flow control, and some special directives as proxy_pass and
fastcgi_pass inside "if" blocks.

Non-blocking behaviour means that evaluating $forbidden variable for

   if ($forbidden) {
       return  403;
   }

may include long query to remote site, and script VM should understand
EAGAIN result when asks for variable, then it should return control
to nginx, and then re-ask variable when it will be available and
continue to execute the script code.
