You may need to ensure your thread safety other approaches. Having said that, atomic will assure that if you are attempting to browse, you receive back some type of benefit.

Structuring an deal with in many atomic columns could suggest obtaining far more advanced code to manage effects for output. A further complexity emanates from the framework not staying adeguate to fit all kinds of addresses.

might bring about unforeseen behavior, when two diverse procedure entry exactly the same variable concurrently

@fyolnish Unfortunately, no: That autoreleases on the thread of the setter, while it ought to be autoreleased within the thread on the getter. Additionally, it seems like there's a (trim) probability of managing from stack because you're applying recursion.
