PHP can be configured via Action instead of FcgidWrapper with
mod_fcgid too.  That is the most direct comparison.

BTW, check the mod_fcgid docs for comments on these two PHP
environment variables.

Use Action with mod_fcgid too so that mod_fcgid processing works
through the same mechanisms as with your mod_cgid setup.

I'll try to find some time today to play with that as well.
Eventually I'd like the documentation to show an Action-based example,
with support for easily switching between CGI and FastCGI for
debugging or other purposes.
