Not sure about the setsid() -  I think you want to stay in the same 
process group so init catches the sigchld and knows to respawn.  Then 
again, init inherits orphan children to clean up their exit status 
anyway so maybe it doesn't matter.  The rest affect the program behavior 
and should stay the same.
