Review comment:
Exactly. When when eventQueue hits the eventTimeoutMs the `null` value
arises (as there is nothing to poll from). When debugging encounter that
`eventTimeoutMs ` could be 0 (if the throttleTimeMs is equal to 0), so if there
is no inmediate events on the eventQueue, the `null` arises inmediatly, and as
it is not caught, the thread stops.
And yes, at the beggining I approached it with a `case null => // Ignore
null event`, which made the class run just fine, but decided to let it generic
to catch some events that may be being overlooked.
What do you think about that?
