Lwt_react.limit does not work as expected

[meadofpoetry]

The documentation states that

[limit f e] limits the rate of [e] with [f].

For example, to limit the rate of an event to 1 per second you
can use: [limit (fun () -> Lwt_unix.sleep 1.0) event].

however limited events occur more that once per second, since after a limiter awakes new event occurs instantly.
