Maybe I'm not being clear.  Let's say bufferedAmount were to reflect the 
number of UTF-8-encoded bytes to be sent, for the sake of argument.

I wait until bufferedAmount is 0, then call send("My text").

What are possible values of bufferedAmount if I examine it right after 
the send() call?  Is 0 a valid possible value?  What about 1?  2? 3? 4? 
5? 6? 7?

Presumably the value will be somewhere in the integer range [0,7], 
right?  Or will it always be 7 after that call in that situation?
