Hash : d1cc47b3
Message : Fixed 2680 - OSX: Replace NSAutoreleasePool with @autoreleasepool Tim McDaniel This patch replaces all use of NSAutoreleasePool with the Apple recommended @autoreleasepool. @autoreleasepool is supposedly more efficient, and since it is scope based it can't be accidentally not released.
