Actually, in newer versions it doesn't have to poll the server. You can
test to see if there are notifications ready to receive and process them
on a timer loop. You're still polling, but only locally within the JVM;
you're not creating any new network activity.
This does *NOT* work if you're using an SSL socket, though, so you have
to be prepared to fall back to issuing "SELECT 1;" or the like for
server-side polling if you can't use client-side-only polling.
