mmm maybe I'm missing something, but why you are treating as error a write that send less bytes than what you asked? Why don't you use your PersistentWrite to make sure to send the entire buffer? In general a flush on a stream has the responsibility to empty the buffer sending the entire content to the socket, so its postcondition should be:

assert( buf_.empty() == true );

Why you allow partial flushing, exposing logic to clients of SendBuffer class? For example, the sync() method on standard streambuf have this semantic.

Obviously I don't know much about the context, so partial flush could be a desired behaviour.

Hope this help!

Cheers,
Fulvio
