I'm not sure it would be worth the effort & complexity to implement IO 
interrupt() for win32. Sun's JRE doesn't implement it, and the docs 
warn against relying on it, so its unlikely that many (any?) 
applications depend on it. My suggestion would be to match whatever the 
latest Sun JDK behaviour is on windows.
