That seems terribly inefficient, forking or restarting incurs a large
performance penalty.

Using the application you're deploying to handle new subdomains instead
of reloading Apache would be easier. For example, Drupal, Wordpress etc.
have multi-site support that runs off a single codebase.

That way you can have a static Apache VirtualHost for *.foo.com and let
your application handle the logic or serving up particular subdomains.
It also keeps things limited to ports 80 and 443 as Ted Leslie pointed out.
