Re-opening the connection each time I want to read the next message is 
completely insane. In particular, with an encrypted connection this will 
require several round trips. IMNSHO, it's insane to optimize for a 
potential problem with a changing IP address, a problem that I will 
never have at work or at home. How do other protocols, e.g. FTP, cope 
with this? I cannot believe that kio_ftp closes and re-opens the 
connection all of the time.
