Are you sure that's right ? It seems to be a memory-gobbling infinite
loop...

How about this:


f = putStrLn "foo"

doEvent f usDelay = do forkIO f
                       threadDelay usDelay
                       doEvent f 1000000

main = doEvent f 1000000

which seems to work.  That makes me suspicious :-|
