Detailed Description

ERCNPublisher sends change notifications to other application instances via JMS server. It observes changes in the default EOObjectStoreCoordinator and creates an ERCNSnapshot object when EOEditingContext saveChanges is performed.

There must be exactly one instance of the ERCNPublisher on the application and registered to the NSNotificationCenter, but its publishChange method will be executed by application's multiple worker threads concurrently. Since JMS session object is limited for serial use (single threaded use), ERCNPublisher prepares a JMS session object per thread so that each worker threads can perform the operation concurrently.
