No but you can for example have a second channel from the pusher to the
observer that signals (in case it cannot push anymore) the latter that the
channel to which it tries to push to is full.
The opposite is true from the consumer, that could signal via a second
channel, when it cannot pull from a channel anymore, that it is empty?
