1) various versions of Yum does not respond to Ctrl-C because doing so
can cause the rpm package database to be left in a bad place.
2) Yum will use a lot of memory depending on how much is installed. Of
course a lot is subjective and needs to be quantified. [100 mb was a
lot on one system and nothing on another.]
3) 4.4 is really old. 4.8 is standard now and 4.9 will be out of the
door by summer (it will also probably be the last 4.x series like the
3.9 was the last of the 3 series.)
