  62 * SA_FLAGS values:

  64 * SA_NOCLDSTOP         flag to turn off SIGCHLD when children stop.
  65 * SA_NOCLDWAIT         flag on SIGCHLD to inhibit zombies.
  66 * SA_SIGINFO           deliver the signal with SIGINFO structs
  67 * SA_THIRTYTWO         delivers the signal in 32-bit mode, even if the task 
  68 *                      is running in 26-bit.
  69 * SA_ONSTACK           allows alternate signal stacks (see sigaltstack(2)).
  70 * SA_RESTART           flag to get restarting signals (which were the default long ago)
  71 * SA_NODEFER           prevents the current signal from being masked in the handler.
  72 * SA_RESETHAND         clears the handler when the signal is delivered.
  73 *
  74 * SA_ONESHOT and SA_NOMASK are the historical Linux names for the Single
  75 * Unix names RESETHAND and NODEFER respectively.
