Jacopo, Erwan,

Sorry I did not see your posts (while editing). 

*Officially vote and release 10.04RC1:* +1
*Shutdown the 09.04 demo and replace it with the 10.04(RC1) demo:* -1. Rather fix issues there and keep alive. It can run with -Xms128M -Xmx512M (with default perm size hence 64m so at most 512+64=576MB. I think we can afford that now. Stable is much more stable at the moment than the trunk (only the leaks above which happen not so often), I don't know for 10.04. I guess we would need a little help from infra if we want to run 3 instances

> It's not quite clear to me how this happends, but I'm quite sure it happens in stable demo and maybe also in trunk. I have also attached a screen-copy with more information
