Description:
------------
stream_socket_enable_crypto() changes the stream to NONBLOCK before it attempts 
the encryption.  I'm assuming this is so the timeout can be tracked, but for 
connections where the handshake doesn't work the process simply chews up CPU while 
the read() repeatedly EAGAIN fails and gettimeofday() is called.

Test script:
---------------
$stream = stream_socket_client("tcp://72.14.204.147:80", $errno, $errstr, 5);
stream_socket_enable_crypto($stream, TRUE, STREAM_CRYPTO_METHOD_SSLv23_CLIENT);

Expected result:
----------------
For the socket to stay in blocked mode.

Actual result:
--------------
