timeout in WP_Http_Streams::request unhandled

[thpani]

WP_Http_Streams::request correctly calls stream_set_timeout().

However, from ​http://us2.php.net/stream_set_timeout it seems that stream_get_meta_data() has to be checked to see if a timeout actually occured during fread()

Tested using netcat as "slow" HTTP server:

while true; do (echo '1'; sleep 15; echo '2') | nc -l 8888 ; done

causes Wordpress to hang in this loop: ​http://core.trac.wordpress.org/browser/tags/3.7.1/src/wp-includes/class-http.php#L899
