ConnectionMap: getConnection() can be a bottleneck
--------------------------------------------------

                 Key: JGRP-1337
                 URL: https://issues.jboss.org/browse/JGRP-1337
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
            Priority: Minor
             Fix For: 3.1


When multiple threads call TcpConnectionMap.Mapper.getConnection() to different target addresses, and some of those addresses are down, then the threads unnecessarily compete for the same lock, therefore socket creations to targets which are up might get delayed by socket creations to targets which are down.
SOLUTION: move the actual creation of a socket out of the lock scope
NOTE: getConnection() may not even need to acquire the lock as the calling code already acquired it.
