Thanks for your information.

It is designed on the prefork. It makes a child process for each
connection to call ap_process_connection() in separated context,
and the parent waits for the completion of this.
In addition, it assigns configured uid/gid on the header_parser hook,
then contents handlers are invoked.

It seems to me that we can share its basic idea and design.
The mpm-itk also has separatable two functionalities:
 1. it makes a process for each connection.
 2. it assigns privileges on a process.

I believe we are now on the right direction.
