[jbosscache-dev] State transfer tests in head

[Manik Surtani]

This was actually from a series of IM and phone conversations I had  
with Brian around RegionManagers and Marshalling/Eviction Regions.

In the 1.x codebase, marshalling regions would queue calls made to  
regions marked as inactive, and then apply these calls when the  
region was activated.  Sort of a way to deal with calls that may come  
in to a cache before the cache has completed transferring state and  
fully joins the cluster.  We felt that with FLUSH in place, we'd have  
a better solution.  If this otherwise edge case starts becoming a  
concern, enabling FLUSH would be the correct solution.
