Yes, it totally is (strace -f) - you just get the PID added..

Right - to it's waiting for child processes (as you're only seeing the  
parent without -f)

This is just totally broken. You can segfault your apache/mod_perl by  
pushing onto @INC or similar..

You are using the prefork mpm, right?

Assuming you are - your distro's mod_perl is totally broken. Try their  
mod_fastcgi instead? Why are you deploying with mod_perl anyway?
