Hey elboulangero,

You might want to change the name, there are already 2 itops that I know
of, that monitor interrupts:

* http://packages.debian.org/wheezy/itop
* http://et.redhat.com/~jmh/tools/xen/itop (this is just a small perl
script, but still...)

Yours provides much more information (works fine on my machine BTW), so
it's a useful addition, but if you just call it itop it's going to be a bit
