[erlang-bugs] SSL socket not sending ssl_closed/ssl_error after a crash

Hi!

Well inet:getopts  had  a somwhat unexpexted behaviour  (although 
documented when I looked a little closer)
"An error tuple is only returned when getting options for the socket is 
impossible (i.e. the socket is closed or the buffer size in a raw 
request is too large). This behavior is kept for backward compatibility 
reasons."  So we will add catch for inet:getopts in ssl.
