Returns true if this.conduit is currently registered for this.events
with this as attachment. Returns false if this.conduit is not registered
with epoll or, when multiple instances of this class share the same
conduit, if it is registered with another instance.
Note that the returned value can be true by mistake when epoll
unexpectedly unregistered the conduit file descriptor as it happens when
the file descriptor is closed (e.g. on error). However, the returned
value cannot be true by mistake.
