So below is something I discovered that seems very strange.

If you run the following code as is, it will run & you'll get stuck in the already documented integral loop.
If you replace the use of events in main with events', the program consumes all available memory & locks up hard.

I know I'm horribly abusing Reactive here, but I don't see why it should fail _so_ ungracefully.

Cheers,

x :: Event () -> Behavior Double

events :: Event ()
events = atTimes [0.1,0.2]

events' :: Event ()
events' = once events

schedule a = threadDelay 100000 >> a

main = do
c <- makeClock
u <- mkUpdater (cGetTime c) (fmap print $ x events)
forever $ schedule u
