/**
* Note: Even though we take various arguments in within the API,
* we don't actually filter anything, since sys-even is either on
* or off. The idea is that the actual Listener themselves will perform
* a final filter pass, so why do the work twice. If we were going to
* use proprietary IOCTLs or some other event plumbing that allowed filtering,
* we could use the passed in arguments to do useful work. In short,
* once turned on, we send events of a given type and rely on
* someone downstream to filter.
