I also think a selinux based (or possible for other secure os) mpm
is a reasonable candidate.

Due to the above limitation, this mpm need to create a process or
thread for each requests, and not to allow keep-alive mode.

If the approach can be acceptable, I will switch to develop the new
mpm approach.
