Initialize the set of remote members whose memory state is critical. This is called when
registering using
{@link InternalResourceManager#addResourceListener(ResourceType, ResourceListener)}. It should
only be called once and very early in this region's lifetime.

@param localMemoryIsCritical true if the local memory is in a critical state
@param criticalMembers set of members whose memory is in a critical state
