....thats what I though, but aparently thats not the case. This maybe do
to a fact that I am starting a child which in return starts a child, hance I
create grandchild. So I dont think system waits fro grandkids to compleate.
after I extract a given cab I need to configure it. So what ends up
happening is that my configure script ends up runing before the cab is
extracted.
