The socket_try_connect() method is one of its callers, but it only ever want one specific action performed. By inlining that action into socket_try_connect() we see that there is not in fact any failure scenario, so there is not even any reason for socket_try_connect to exist. Just inline the asynchronous connection attempts directly at the places that need them. This shortens & clarifies the code. Signed-off-by: Daniel P.
