The question is whether you want to use it. Perl w/ithreads not only slows 
things down and requires more memory, while ok for dev purposes, it will 
probably won't scale well in production. The reason, cloning a new perl 
thread under the server with many modules loaded and busy CPU may take... 
a few minutes.

We should really wait till perchild and/or metux [1] are completed, which 
is when you will be able to use a scalable solution for independant 
vhosts. The problems is that it doesn't seem that anybody is working on those.

The best solution for now if you have conflicting namespaces, is to run 
separate mod_perl servers for each host.
