Instances must round up for correctness.ÁWe hold the CallbackHandle in an MVar so we don't race on update/cancelation and executing the callback. Updating or canceling holds the lock, which is also required to export the action. rOur actual callback data. CallbackCancel so that we can know if we're canceled even if we raced with execution.?Delay a until at least the specified amount of time has passed.Delay until a specific  Œ has occured (at least once). This is slighly confusing, as we can't guarantee we don't return only after the second occurence of the  J under certain leap second handling regimes. Consider for example when Ð is called during a leap second occurence, where the system clock jumps back and repeats the second. As there is no indication the time has already passed once, we must wait until the second occurence.QRun an monad action for at least a specific number of seconds, but not much more.uRun a monadic action until it produces a result or a specific time occures.
