• SSL: Attempting to send empty data using the
  :meth:~socket.socket.sendall method of a gevent SSL socket that has
  a timeout now returns immediately (like the standard library does),
  instead of incorrectly raising :exc:ssl.SSLEOFError. (Note that
  sending empty data with the :meth:~socket.socket.send
  method does raise SSLEOFError in
  both gevent and the standard library.) Reported in #719 by
  Mustafa Atik and Tymur Maryokhin, with a reproducible test case
  provided by Timo Savola.
