ruby--ruby/ext/openssl/ossl_ssl.c
gotoyuzo a579d8bf68 * ext/openssl/ossl_ssl.c (ossl_ssl_read, ossl_ssl_write): should
call rb_sys_fail instead of rasing SSLError if SSL_ERROR_SYSCALL
  occured.

* ext/openssl/lib/openssl/buffering.rb (Buffering#fill_rbuff):
  should rescue Errno::EAGAIN.

* ext/openssl/lib/openssl/buffering.rb (Buffering#each): fix typo.
  suggested by Brian Ollenberger.

* ext/openssl/lib/openssl/ssl.rb: set non-blocking flag to the
  underlying IO.
