There something called Jails, and SE Linux groups, that isolates user processes regardless programming language of choice. Even then Perl was there with almost all things needed to create pages and daemons for most of the work, that can be automated. If you need to embed script you can, in any language. PHP just solved the problem with the massive competition, utterly fuck anything that has been made with it.
Heck, you can even make simple limited VMs to provide all the necessary components you need for a client. That is why projects like OpenStack are getting so much poularity.
