Thank you for your help. What i really care about is how well the L4Re is providing. Because i have a willing to port a search engine or a hadoop framework on L4Re to see if i can gain much more performance benifit. 
In L4Re, you have already present uclibc and pthread for programmer. But it seems like that I need to build the application (hello world) with the L4Re, and after that i can boot the system and run the app.
Can i just build and run my applications on L4Re after the L4Re+Fiasco.OS has been boot? Is there any tools developed to dynamic build and load applications? (i'm not refereing to the Ned which inits and loads compiled apps.)
