Probably because if you interrupt packages in the middle of updating, you 
have an excellent chance of FUBARing your entire system.

This has been a long standing problem with rpm. If you interrupt a long 
update, you'll end up with both the old and the new version of affected 
packages installed. That's always fun to clean up.

Don't do that.
