Detailed Description
template<typename pagemapT>
class moost::kvds::KvdsPageMapShared< pagemapT >
A pagemap that allows multiple pagestores to share the same pagemap. Useful if you want to store the store entity in a resource stack to make sure there are not multiple instances of the pagemap being kept in memory. Shared pagemap simply works by wrapping a pointer to an instance of a pagemap. Different stores can be assigned the same pagemap by instantiating them with this shared pagemap and then assigning them all the same pointer handle. *** This class is NOT thread safe *** NB. There is no point in making this class thread safe since the pagestore that uses it is also not threadsafe!

Because we need this to act like a normal pagemap we need to create an instance of the pagemap we're sharing on demand. We don't want to create it at construction in case we're going to share with another and we can't put a liability on the store to create it because the store knows nothing about the implementation detail of pagemaps.
