Before @autoreleasepool a fairly common pattern in a try catch would be the following

NSAutoreleasePool *aPool = [[NSAutoreleasePool alloc] init];
@try {
	
}
@catch (NSException *anException) {
	
}
@finally {
	[aPool drain];
}

I believe the theory being that you try to clean up what you can in the @finally even though you would likely still leak some objects.

With @autoreleasepool there doesn't seem to be a way to do this:

Is it fair to say that the drain in the old style was more handwaving than helpful or is @autoreleasepool worse in this regard than the object version?
