Overview

Note:

‘a = b` is not a thread-safe operation on `Concurrent::Set`. It reads Set `a`, then it creates new `Concurrent::Set` which is union of `a` and `b`, then it writes the union to `a`. The read and write are independent operations they do not form a single atomic operation therefore when two `=` operations are executed concurrently updates may be lost. Use `#merge` instead.

A thread-safe subclass of Set. This version locks against the object itself for every method call, ensuring only one thread can be reading or writing at a time. This includes iteration methods like ‘#each`.
