I cannot see there is anything “advanced” MRR (manual retain-release) going on
in:
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
insert your viewer code here
[pool release];
That can’t be handled with @autoreleasepool, if you even need to handle it
outside the main thread autoreleasepool
In fact the above is a classic example of the old garbage collector in action.
