Hello;

I want to put some data into the user info of an object store co- ordinator and then pull it out again in notifications.

	ec.lock();

	try
	{
		ec.rootObjectStore().setUserInfoForKey(xyz,"foobar");

		try
		{
			// do some editing context foo here!
		}
		finally { ec.rootObjectStore().setUserInfoForKey(null,"foobar");
	}
	finally { ec.unlock(); }

That should be safe should it not or am I playing with fire?


Define safe. ec.lock() does not lock the root object store, so other ec's can also set / clear foobar while you are in this code.
