Any code suggestions on reducing memory usage would be much  
appreciated.  But remember the following:
1.) PHP is a high-level language, and was not designed for programmers  
to easily manage memory usage.  mallocs, etc. are handled by the  
interpreter and is transparent to a PHP script.  So complaining about  
memory usage, without providing us pointers on how we (as PHP coders)  
can reduce memory usage, is not tremendously helpful.
2.) You don't think that, for example, a windows program uses a  
similar amount of memory to view a message?  Try running thunderbird  
and looking at memory usage when viewing a 1.5 mb message.
