The default configuration is also quite different.

There are two CGI modules in Apache HTTP, mod_cgi and mod_cgid which 
use different approaches to start CGIs. Both Debian and Redhat ship 
both modules, but there may be differences which module is selected by 
default. On Debian, mod_cgi is selected with MPM prefork and itk and 
mod_cgid is selected with MPM worker and event. I guess that is the 
difference you are observing.

Redhat and Debian also differ in which patches have been applied on 
top of the original code, but those differences are likely small. In 
Debian, there is README.Debian in the docs dir that should describe 
the behavior differences.
