Well, its my server and there is/will always be just me on it, so i'm 
not worried
This also isn't for a 'security' minded problem ( i know a lot of 
people like to try and make each user run scripts under their own uid )

This is for performance, and actually an often used approach for 
production systems

Vanilla apache will sit on port 80 as a frontend proxy and static 
content handler
Dynamic apache(s) will sit on other ports and handle dynamic content

in my situation, the performance gains are in 2 areas:
a- memory --
	modperl enabled apache is trimmed down to only the apache/perl 
elements needed
b- performance --
	dynamic generated content is /almost/ instantly transferred to the 
vanilla proxy, freeing up the seconds wasted by a slow connection or 
disconnect

There's some info here that is a better description than me:
