Great. I poked down through the ECM code and it makes sense what's going
on now. Is the configuration just part of my regular xconf? i.e.
<guardian pool-min="5" pool-max="25"/>
More importantly I'm curious as to why excalibur.datasource internalizes
the pooling rather than utilize PoolableComponentHandler. Is it simply
so there is no dependancy there?
Thanks.
