Pure code can always be safely asynchronously interrupted (even code using state like the ST monad), and IO code can be made to interact correctly with thread termination simply by using appropriate bracketing functions that would handle normal IO exceptions.

Ertugrul's advice is still correct. I'd wager there are very few concurrent applications that could survive a killThread without disaster. People simply don't write or test code with that in mind, and even when they do, it's more likely than not to be wrong.

That's surprising to me -- this is how we kill the Snap webserver (killThread the controlling thread...). G -- Gregory Collins
