Description:
------------
It would be great to pass the string by reference in fwrite.  Otherwise it makes a copy of the data.  This is a problem for very large files.

PHP Warning:  Call-time pass-by-reference has been deprecated - argument passed by value;  If you would like to pass it by reference, modify the declaration of fwrite().  If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file.  However, future versions may not support this any longer.  in /home/pearcec/saturn/www/include/file/cnFileBlob.inc on line 156

Reproduce code:
---------------
fwrite($fp, $inContents);

That is not true, PHP does not copy the data in this case. PHP does a copy on write, and because the fwrite function does not change the string nothing will be copied (it's actually more efficient then passing by reference in this case).
