It's primarily an aesthetic benefit. From

- (IBAction)analyzeDocument:(NSButton *)sender
{
NSDictionary *stats = [myDoc analyze];
[myModel setDict:stats];
[myStatsView setNeedsDisplay:YES];
[stats release];
}
becomes
- (IBAction)analyzeDocument:(NSButton *)sender
{
dispatch_async(dispatch_get_global_queue(0, 0), ^{
NSDictionary *stats = [myDoc analyze];
dispatch_async(dispatch_get_main_queue(), ^{
[myModel setDict:stats];
[myStatsView setNeedsDisplay:YES];
[stats release];
});
});
}
Two more lines of code, and it will execute that block in another
