I think it is of yum users' interests when making language decision.
There is another example of bad usability for handling CTRL-C,

[root@localhost ~]# yum -d 10 update
Config time: 0.107
Yum Version: 3.2.19
COMMAND: yum -d 10 update 
Installroot: /
Reading Local RPMDB
rpmdb time: 0.001
Setting up Package Sacks
pkgsack time: 0.003
Setting up Update Process
Building updates object
^C^C^C^C^C^C^C^C^C^C^C^C^C^C^Cup:Obs Init time: 0.733
^C^Cputting kpathsea in complex update

...

You could see from the above, I have to hit CTRL-C more than 10 times
in order to cancel the operation. Far more than tolerant for reasonable
user experience. Is it the same thing as the Python socket handling
bug?
