No, it's better to make it wait for the user to start worrying and press 
the equivalent of Ctrl+C from the GUI, unless the patch is supposed to run 
unattended.

Rudely dropping the stack has lots of potential to cause crashes, in 
addition to be very unportable (you need one version of it per OS/CPU 
pair). If you are interested in that, I have just wrote several mails on 
that topic.

As long as the user using them knows the problems that they are getting 
into by using that feature, everything is fine.
