Commit Message

Fix SocketStream.send() writing to a paused transport after a cancelled send (#1299)

SocketStream.send() went straight to transport.write(), which appends to the transport's write buffer without ever offering the data to the OS whenever that buffer is non-empty. A send() cancelled while awaiting the write event
leaves exactly that state behind: buffered data and a paused protocol. The next send() then piled its data on top, so repeated cancellation could grow the buffer without bound despite its zero high water mark.

Wait on the write event before writing, as the datagram sockets do.
