[suPHP] SuPHP recursive forking

[J.D. Tysko]

I used env -i with spectacular results.  It worked perfectly, with the
exception of resetting the environment (so me of which is kind of
needed).  Next I thought I could just modify the environment like Jeremy
said, and I have a small snippet where I use something like:
    $tmp = getenv("VAR");
    putenv("VAR");
    shell_exec(...);
    putenv("VAR=".$tmp);

But with an array to hold all of the saved vars, but I can't seem to
find the right environment variables to unset.  Can someone give me a
list of CGI variables which should be unset to allow PHP to work as a
CLI version, but not mess up anything else?

Thanks,
