I'm not the original poster but I could envision a use for this on our
systems - e.g. most of our web servers can work with Apache Worker MPM
but one of them has a compiled apache module which can only work with
the Prefork MPM. If we had to run all of them on the same OS image
(e.g. as a small appliance or a private development environment) then
I think such a trick would be useful to us.
