OpenEJB Question

[Manu George]

Hi,
        In the class org.openejb.deployment.AbstractContainerBuilder there is a method

    protected SoftLimitedInstancePool createInstancePool(InstanceFactory instanceFactory) {
        return new SoftLimitedInstancePool(instanceFactory, 1);
    }

What pool is this? Is this the pool of Enterprise bean instances. Why is it set to 1?
Where in the code is the parameter  set  for the  pool size for EJB  (Stateful or  Entity).

Thanks
Manu
