Of course there is a reason. My application is quite complex(4000+ 
lines in one card), it is continually parsing a feed from a telnet 
connection... multiple times a second. Blocking operations of any kind 
are not favorable in situations like this. The rest of the application 
has to continue its duties while FTP communications are ongoing, else 
things get... backed up and out of sync. That said, I've found getting 
the directory listing to be as fast as you say... but then, the server 
is currently local. That may not always be the case.
