Being "reliable" includes giving up - and saying so - when "slings and arrows" 
intervene.

Perhaps I picked up the wrong emphasis from your original post. I took it to be 
a concern over FTP rather than a concern over the Internet. As you have 
demonstrated to yourself, the Internet - as they say these days - 
has "reliability issues"! At some point, TCP will give up retrying to 
compensate 
for the unreliability of the underlying TCP connection path.
