Well, it also has advantages of running 2 apaches on the same machine.
We have a high traffic site hosted on one machine and one apache is only doing
mod-perl stuff and the other apache just serving images.
That was developed before I joined the company, but folks told me that it
*indeed* has a performance gain, because the image-apache doesn't have mod-perl
enabled.
