AtomicIndexFlag
A mixin trait that implements index flag behaviour using atomic integers. The setIndex operation is wait-free, while conditional set operations setIndexIfGreater and setIndexIfLesser are lock-free and support only monotonic changes.

Sends an abort signal to other workers.
Abort flag being true means that a worker can abort and produce whatever result, since its result will not affect the final result of computation. An example of operations using this are find, forall and exists methods.
