(And I know, I've suddenly switched to OSI-speak to avoid the word "connection" here) And is this done merely if associations are idle, or only if there are no current associations? It makes a huge difference to the viability of the 770 or N800 as a platform for mobile email, and I'd have thought it'd degrade the user experience for XMPP as well. Take a look at the highly readable http://www.ietf.org/internet-drafts/draft-ietf-lemonade-deployments-04.txt for some general guidance for the mobile email case.
