Tipically in case of error on sendall() you don't want to resend anything
because most of the times it's a disconnection error (and never, say, a
"retry" error such as EAGAIN).
The use case I'm thinking about, and which would probably be the most
common one, is to figure out how much data was sent (via exc.sent or
something), add it to "total", reconnect and resume the transfer from where
you left.
