SetLatch is designed to return quickly if the * latch is already set. * - * Presently, when using a shared latch for interprocess signalling, the - * flag variable(s) set by senders and inspected by the wait loop must - * be protected by spinlocks or LWLocks, else it is possible to miss events - * on machines with weak memory ordering (such as PPC). This restriction - * will be lifted in future by inserting suitable memory barriers into - * SetLatch and ResetLatch. - * * On some platforms, signals will not interrupt the latch wait primitive * by themselves.
