The first time I used it was for precisely this reason - some buggy PHP code opened hundreds of connections to a dev
serverwhich then remained open doing nothing except wasting resources. It was particularly useful in that case as I
didn'thave access to the web server at the time. 

Shortly afterwards I added support to pgAdmin's server status tool which has proven quite handy (although I will admit,
mainlyfor canceling ather than terminating). 

I don't know the details of how it works, but is it any worse/better than 'kill -9' (which iirc is no longer considered
anabsolute no-no)?
