| H A D | signal.h | diff 29340 Sat Sep 13 17:42:29 MDT 1997 joerg 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. ;) Reviewed by: bde |
