[jbosscache-dev] RegionManager

[Manik Surtani]

I'd go for the latter.

We shouldn't assume that the caller is looking for the parent's  
region and return that, since there are very valid use cases for  
subregions.

Re: merging the different types of regions, this is what we discussed  
some weeks back, this is precisely the intention.
