You cannot absolutely state that the limits are the same, even if
the uid is the same.  You either need to examine Apache source and
mod_cgi to see how it deals with limits and invoke CGI programs.

I.e.  The shell and Apache are two different environments for
invoking a program, and each environment may invoke programs and
set limits differently.

One test that can be done is to write a C-based CGI program that
just outputs the effective limits (do _not_ invoke a shell callout
to get such information since the shell could modify these limits).
Do a 'man 3 getrlimit' for the C library calls for to use.
