Warmth of a connection (cwnd) is estimated by the amount of data written to the socket.

Choosing the warmest connection would mean faster resource load times. 

idle time is the time a socket has remained idle (no http requests being served on it). 
Probability of server resetting a connection increases with idle time duration. 

Using a cost function that takes into account bytes transferred and idle time to pick best connection to schedule http requests on.

Reverted: http://codereview.chromium.org/7255002 :(

Have fixed 2 things since:
1. Removed LOG(ERROR) from http_basic_stream.cc that was causing layout tests to fail.
2. Initialized class variables in http_basic_stream.cc that was causing uninitialized memory bugs in valgrind: http://code.google.com/p/chromium/issues/detail?id=87423
