  Log:
  The current rusage code show peculiar problems:
  - Unsafeness on ruadd() in thread_exit()
  - Unatomicity of thread_exiit() in the exit1() operations
  
  This patch addresses these problems allocating p_fd as part of the
  process and modifying the way it is accessed.
  
  A small chunk of this patch, resolves a race about p_state in kern_wait(),
  since we have to be sure about the zombif-ing process.
