I like the idea of firing an event when bufferedAmount becomes zero. It
might be good to have a method to configure to "target buffer size" that
the application wants, in case it's more than zero.

In the server-side world, Twisted works like this: when more than 2**16
bytes (by default) are buffered, it calls pauseProducing on the "registered
producer", and when it goes below this mark, it calls resumeProducing.
