yum does not consistently stop when CTRL + C is pressed

Issue

• Yum does not have the same behavior as other commands when pressing Ctrl-C to stop the shell command:

  # yum update
  # yum install <package1> <package2>
  

• Pressing Ctrl-C is SUPPOSED to skip to the next mirror. Pressing it twice in quick succession should drop you from the run. But this, sometimes, doesn't happen or it doesn't happen immediately: it's waiting before exit to the shell.
