[Zope] memory-leak, would the chrism-setrlimit "patch" help?

Hi, I'm just wondering if anyone knows why this way of restarting zope in case of memory leaks never made it to the HEAD? http://cvs.zope.org/Zope/Attic/z2.py.diff?r1=1.56&r2=1.55.10.1&only_with_tag... AutoLance used to work nice, but seems not to be updatead any more, so it's no option for Zope-2.7 and linux-2.6. I've seen some suggestions for external tests, like http://www.zopewiki.org/CheckZopeMem, but chris' way seems to be so much simpler. Does anyone know if the setrlimit solution has problems? Thanks, Sascha
