Yes, that does seem right. Previously it would never be concurrently modified, because it was always locked by the critical section, but now we read it without locking, and we certainly don't want that optimized away. The mask is only ever written by the main thread, never by the signal dispatching thread. So I think that one could do without. //Magnus ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
