It's a valid suggestion for certain circumstances, but not in ours -
we use our own irons to run multiple xen guests. Some of them are
short on RAM/CPU/Disk and being able to give each developer (or
customer) their own entire software stack on a single image is very
useful.

Not in CentOS - Apache comes compiled both with pre-fork and worker
MPM binaries and you can pick which one to start from the init script
by commenting/uncommenting a setting in /etc/sysconfig/httpd. I guess
that creating a similar init script which starts apache with other
configuration parameters could be enough to run both instances in
parallel in the same environment.

That said - I don't know the situation or motives of the original poster.
