[swift-corelibs-dev] NSObject's performSelector(inBackground:with:) doesn't feel right in Swift 3

[Philippe Hausler]

Those methods should probably all belong to the same family of `perform` but it matches the method naming of:

open func performSelector(onMainThread aSelector: Selector, with arg: Any?, waitUntilDone wait: Bool, modes array: [String]?)

But perhaps the naming family should belong to this one:

open func perform(_ aSelector: Selector, on thr: Thread, with arg: Any?, waitUntilDone wait: Bool)
