How to limit the number of concurrent CGI script invocations in Apache 2.2?

How can I limit the number of concurrent CGI invocations in Apache 2.2.x?
More specifically, my problem is this: I have Apache hosting a Bugzilla instance and other stuff on one server. There's very little legitimate concurrent use of Bugzilla. However, it's trivial to mount a Denial of Service attack on the whole server by ignoring robots.txt and simply fetching a lot of bug pages that fork a process and hit a database.
