Ya, obviously this doesn't parallelize the connect, just the request. 
Unless you're doing SSL, the only blocking thing Net::HTTP.connect does 
is the underlying TCPSocket.open.  If that is your bottleneck and you've 
already set open_timeout as low as you can go, then you'd have to patch 
deeper to get Net::HTTP to use connect_nonblock as per 
http://www.ruby-doc.org/core/classes/Socket.html#M002091 instead of 
TCPSocket.open
