more relevant is a large multithreaded (or async model with many connections per thread/process) webserver spawning cgi. otherwise you pay the costs of duplicating the mm and even if you use F_CLOEXEC (which has a cost-per-connection) you have to pay for scanning the open fds.
if you look at such webservers they tend to have a separate process just for the purpose of spawning cgi/etc. and use some IPC to pass the data to the cgi spawner.
