replacing CI's log_message global function in common.php

Hi all,

I would like to substitute CI's log_message function defined in common.php by my own version of that function with the same name so that all existing calls to log_message (Within CI or within my code) will continue to work.

The purpose is for the new log_message function to call my own logging solution which IS NOT an extension of the CI_Log Class. 

I know I can create a MY_Log Class and override the CI_Log Class, but if possible I would like to redirect the messaging right from the entry point (the log_message function).

Any suggestions on overriding CI global functions?

I am all ears  :-)
