Kill runhaskell process on Windows

I've got a haskell program I'm executing with runhaskell on Windows. The program sits in an infinite loop listening on a network socket. I can't kill the program with ctrl-c, ctrl-d or ctrl-z and my keyboard doesn't have a break key.

Is there anything else I can try to kill the process without havi开发者_StackOverflow中文版ng to resort to task manager?

taskkill /IM runhaskell

I'm guessing at the process name here; if not runhaskell replace it with what it really is.
