it is useful for people on low bandwidth connections as it makes it
easier to get packages without having to cut a large download in
between and having it download all over again.

May you suggest another way ? As I mentioned ordering was happening
between predownload and postdownload hook .. so I could not figure out
a better way, may you suggest?

Moreover I was also plaining to do a download-by-deps i.e say 'yum
install foo bar' will download foo and all its deps first and then bar
and remaining deps for same reason as mention above.
