  Log:
  Implement SA_NOCLDWAIT.
  
  The implementation is done (unlike what i've originally been
  contemplating) by reparenting kids of processes that have the
  appropriate bit set to PID 1, and let PID 1 handle the zombie.  This
  is far less problematical than what would seem to be ``doing it
  right'', for a number of reasons.
  
  Of our currently shipping PID-1-intended programs, 50 % fail the above
  assumption. ;-)  (Read this: sysinstall doesn't do it right.  This is
  no problem as long as no program called by sysinstall actually uses
  SA_NOCLDWAIT.)
  
  ToDo:		. clarify the correct SA_* flag inheritance, compared
  		  to other systems,
  		. decide whether the compat cruft (osigvec(9)) should
  		  deal with new system additions or not,
  		. merge OpenBSD's SA_SIGINFO implementation. ;)
