What do you mean by "sane Perl apps shouldn't use CGI"?

Well, I guess "sane" might not have been the best choice of words. By that definition, I am not even sane myself. Of course, not many people would argue with me about that, so perhaps the word still makes sense. ;)

Maybe I should have said, "for any Perl web apps where performance matters, sanity dictates the use of mod_perl instead of plain CGI. But for web apps where performance doesn't matter, CGI might be ok."
