TCP connections are more reliable than UDP; that does not mean they are 
"reliable", full stop.

I agree that most ugly, stupid software too quickly resorts to dumping a 
connection. But it sounds like you're just arguing the other, equally 
wrong, extreme. Software that doesn't take into account that TCP 
connections often do either fail completely or stall for so long as to 
constitute a failure to, you know, a normal person who's trying to get 
something done interactively, is just wrong. Patience is usually but not 
always a virtue.
