I'm not protecting / limiting it via IEFUSI (yet?), but I do have a default specified in SMFPRMxx. They asked me what a good default value was and my reply was the same as has been discussed previously on ibm-main - "no one knows yet". Most of my LPARs have MEMLIMIT(10G), but some of the smaller ones have MEMLIMIT(5G). My fear is that even 10G is perhaps too small, but I haven't run into any problems yet (z/OS 1.6, WAS 5.1, DB2 V8).
