The issue is that if you don't have robust cross process mutex, you may get into a condition where you have a bad mutex sticking around (say after a child that holds the mutex SEGVs). Bad things start to happen then. If we have robust, we definitely want to use it. I'm not sure whether we want to use pthread_mutex_t for cross process if we don't have some form of robust locking. (Solaris's setrobust_np is non-portable - as the name implies - does AIX have something similar? Is it the default behavior?) -- justin
