stop current execution by interpreter

[luxsln]

Hi..

I want to implement something very close to the Keyboard Interrupt for my app.

what i am trying to do is this :
1) I have pushed a command to be executed to the interpreter. (say from a user given script file)
2) now, user finds that there is some infinite loop in that and so needs to stop
3) how do i interrupt and tell the interpreter to stop wat it is currently doing ?

note: all this is happening from a new UI.. which has wx.py.shell embedded.

thanks in advance,

lux
