Apart from limiting the CGI programs, another approach would be to

resources.
Would this be limited to the scripts themselves, or to the server as a
whole?
It can do either the entire server, or for specific handler types:

This way you could disable CGI when your LA is above 10, and then
disable everything when your LA is above 100:
LoadAvgMaxByHandler cgi-script 10
LoadAvgMax 100
