This is not possible.

The solution, here, is having Nginx to call seteuid/setegid instead of
setuid/setgid in ngx_worker_process_init.
In this way the child process can call seteuid(0) to become root again,
and then, finally, setuid(xxx) to become the effective user for the CGI.
The problem, of course, is that an external module can call seteuid(0)
to become root, and this is not acceptable.
