Log:
  dup(2): Remove incorrect sentence about getdtablesize().
  
  There are no getdtablesize() bounds on the file descriptor to be duplicated;
  it only has to be open. If the RLIMIT_NOFILE rlimit was decreased after
  opening the file descriptor, it may be greater than or equal to
  getdtablesize() but still valid.
