Module Net::SSH::ForwardedBufferedIo

  1. lib/net/ssh/buffered_io.rb

Fixes for two issues by Miklós Fazekas: 

* if client closes a forwarded connection, but the server is
  reading, net-ssh terminates with IOError socket closed.
* if client force closes (RST) a forwarded connection, but
  server is reading, net-ssh terminates with [an exception]
