[swift-corelibs-dev] Asynchronous Operations

On Darwin, asynchronous usage of Operation is supported via KVO

Because KVO is only available on Darwin platforms,
swift-corelibs-foundation currently does not support asychronous
Operations, and there is a comment to that effect:


My understanding is that it's unlikely KVO will arrive on Linux any time
soon, so this leaves us with a problem in Operation.  Asynchronous usage of
Operation is an important feature.

Is there any way that we could support asynchronous operations in
swift-corelibs-foundation, in the absence of KVO?

Might it be acceptable to add extra temporary public API to enable this?

Many thanks,

Ian Partridge
