Keep sending want lines if the server doesn't anwer a flush

Browse Source 
Some servers take a long time to answer and expect us to keep sending
want lines; otherwise they close the connection. Avoid this by waiting
for one second for the server to answer. If the timeout runs out,
treat is as a NAK and keep sending want lines.
