Portable keyboard signal handling

I do too, but that module has absolutely no documentation on the web
(http://www.haskell.org/ghc/docs/latest/html/libraries/base/GHC-ConsoleHandler.html),
so rather unsurprisingly I missed that entirely!

I also need to raise Ctrl-C on a process I have started from Haskell,
so if that could be also done in a portable way then I'd be happy :)

Thanks

Neil
