[imp] Downloading an attachment

And if you look at the INSTALL documents, it states that NO memory  
limit should be set.  So you are on your own when using PHP w/a memory  
limit specified.

If people would like to submit patches/suggest improvements as to how  
we can improve our memory performance, we would obviously be more than  
willing to take a look and improve this.  But we have made this call  
for improvements many times in the past, and to this day all of those  
who are so vociferous in bitching that "Horde sucks!  it uses too much  
memory!  the coding stinks!" have done absolutely nothing to help with  
improved results.

In so many words, PHP is a high-level language which (by design) is  
meant to hide many OS-level details from the programmer (i.e. memory  
management).  So programming in PHP with an eye toward reducing memory  
is much more transparent than it would be in other languages (i.e. C).
