Obviously; no _real_ Unix hacker would use a program option when he
could use a shell hack (and 20x as many extra keystrokes ;)

Lack of generality.  I don't do that kind of thing very often; I may
or may not have ever noticed that ncftp has that option.  Other ftp's
doesn't AFAIK.  Not to mention other programs; due to a DNS admin

 sleep 900;
done
