/**
* Ref/unref can be used to add or remove a reference count on the event loop:
* Every watcher keeps one reference, and as long as the reference count is nonzero,
* ev_run will not return on its own.
*
* This is useful when you have a watcher that you never intend to unregister,
* but that nevertheless should not keep ev_run from returning. In such a case,
* call EventLoop::unref after starting, and EventLoop::ref before stopping it.
*
* As an example, libev itself uses this for its internal signal pipe:
* It is not visible to the libev user and should not keep ev_run from exiting if
* no event watchers registered by it are active. It is also an excellent way to do
* this for generic recurring timers or from within third-party libraries. Just remember
* to unref after start and ref before stop (but only if the watcher wasn't active before,
* or was active before, respectively. Note also that libev might stop watchers itself
* (e.g. non-repeating timers) in which case you have to EventLoop::ref() in the callback).
*
* Example: Create a signal watcher, but keep it from keeping ev_run running when nothing
* else is active:
* <code>
* $sig = new libev\SignalEvent(libev\SignalEvent::SIGINT, function()
* {
* // Do something
* });
*
* $loop->add($sig);
* $loop->unref();
*
* // For some weird reason we want to unregister the above handler
* $loop->ref();
* $sig->stop(); // or $loop->remove($sig);
* </code>
*
* @return boolean
