> The balancerSwitch as in both 0.90 and 0.92.1 is implemented in such a way that it is
impossible to retrieve its value without changing it:
> /**
> Turn the load balancer on or off.
> @param b If true, enable balancer. If false, disable balancer.
> @return Previous balancer value
> */
> public boolean balanceSwitch(final boolean b);
> It would be nice to have a way to just get the current state.
