Pull up revision 1.21 (requested by thorpej):
  Change fdalloc() to return ERESTART if reallocation of the
  descriptor array was needed, and change uses to handle that
  condition.  Make finishdup() close the descriptor in the new slot
  if it exists, and change sys_dup2() accordingly.  Closes a race
  condition when using kernel-assisted user threads.
