PutFromLoadValidator read stale data from the cache.

Hi,

This problem actual started as a investigation on the JBoss Cache in a cluster, but we believe this also exists in Infinispan. We able to reproduce it with Infinispan also. It's a combination of a problem in the Hibernate 2LC and Infinispan so I might not be the right place to create this jira.

This is what we have been able to find out so far. "When an invalidation event arrived on node #2 there is no callback to the 2LC layer that will make sure to call invalidate. Another problem we discover was if a collection is invalidated on node #1 twice in a row the second time no invalidation event is broadcasts to node #2, and that’s a problem because in between invalidation event #1 and #2 the PutFromLoadValidator is called on node #2 and this makes it read stale data from the cache.

The forum link contains a possible patch for Infinispan and Hibernate 2LC, but there might be other areas in the code the patch could introduce a problem for
