Yes and no... 1) KVO and multiple thread gets ugly quick, 2) using NSCondition/Lock may make more sense, 3) using just a volatile BOOL could be enough depending on how lazy the detection of the ivar can be, 4) look at using OSAtomicXxxx functions [1]. Note OSMemoryBarrier is just an ordering construct (only really applicable to PowerPC at this time) not an atomic operation or locking construct. -Shawn [1] <http://developer.apple.com/documentation/Cocoa/Conceptual/Multithreading/ThreadSafety/chapter_5_section_6.html> _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
