As it must because the outgoing buffer is full. You must save the 
client's state and return (=yield) at this point. When a portion of data 
is sent (taken from the buffer) the client's Sent primitive procedure 
will be called and from there the client can restore its state and 
continue. You cannot loop, it is pointless. You must yield.

This was the essence of the whole discussion about the state machines 
vs. co-routines. Writing clients is *difficult*.

Sure in many cases there exist buffer size that guarantees sending [*]. 
This is not always the case. When not, the client must drop connection 
if it cannot sent. So, you will have unreliably working clients.

[*] Many industrial protocols have bounded the packet size and work in a 
query-answer manner. For these the output buffer size is roughly the 
packet size.
