Comment (by awbauer):

 We're seeing the same issue here. In our current case, HTTPS POST
 connections to https://www.google.com/recaptcha/api/siteverify (with
 content in the body) time out 100% of the time. When the POSTs are
 submitted without body content, the requests complete no problem.

 Commenting out those lines in class-http.php has been the only fix that's
 worked for us.
