Sycnrhonized operations that change the value of the cluster wide cap. Added cleverRecap(...) that determines the recap value of the cluster at a much finer level, taking into account the average load on each node in the cluster. Bug fix in cap.go -- closed the session once capping had been done. This prevented from running out of file descriptors.
