It's easy enough to launch an NSTask and not wait for it. Just discharge
whatever ownership responsibilities you have received, as per proper memory
management techniques. That is, if you used a method which gave you ownership
responsibilities, like +alloc, then invoke -release to balance it. After that,
just forget it.
Really, it can be as simple as one line:
[NSThread launchedTaskWithLaunchPath:@"/path/to/program"
arguments:[NSArray array]];
