StreamWrapper Class

Another workaround for a .NET bug (http://social.msdn.microsoft.com/Forums/en-US/netfxnetcom/thread/f4c3d019-aecd-4fc6-9dea-680f04faa900)

NetworkStream

• non-blocking Read() returns 0 bytes when there is nothing to read
• IOException when "the underlying Socket is closed." -> reconnect
• Write() is thread-safe

SslStream

• >non-blocking Read() throws IOException -> no need to reconnect
• after the exception a subsequent non-blocking Read() (when there is nothing to read) returns 5 bytes of SSL keep-alive data (23 3 1 0 17) 23 is TLS application protocol, 3 1 means TLS 1.0, 3 0 would be SSL 3.0
• Write() is NOT thread-safe

Unify the behavior to NetworkStream behavior.
